AF93/IS903 Instruction Manual S-2

Safety Danger High Voltage Internal parts of the drive are at line voltage when AC power is connected to input terminals. This voltage is extremely dangerous and can cause death or serious injury. When the supply is disconnected from the input terminal block, it will take up to 10 minutes before the DC bus capacitors are discharged to a safe voltage. To ensure the voltage is safe, monitor the capacitor discharge with a digital voltmeter connected between the ÒAÓ and ÒBÓ terminals on the capacitor assembly as described in Section 5, Troubleshooting. Do not work on the drive until the capacitors have completely discharged. Do not attempt to discharge the capacitors by short circuiting the bus.

Danger AF93/IS903 Adjustable Frequency Drives are not suitable for use in an explosive atmosphere or in a ÒHazardous (Classified) Location.Ó See Article 500 of the National Electric Code.

Caution A hazard of potential damage to your drive, due to overheating, exists if your drive is operated at a line impedance below 1%. You must ensure that the input line power has an impedance of at least 1%, and less than or equal to 5% for proper drive operation. Damage may occur if the source impedance is less than 1%. If the source impedance is more than 5%, the drive may not provide rated output voltage. Install a AF93/IS903 1% input line reactor if your line impedance measures below 1%.

Warning Carefully consider the application when you select AF93/IS903 Adjustable Frequency Drive components and options and associated drive motor. You must ensure that your application meets the restrictions stated in this manual and the nameplate of your drive. Failure to observe these restrictions can cause personal injury or damage to personal property and could void your warranty: ¥ Make sure selected equipment meets the requirements of the NEC, NEMA, UL, CSA, IEC, IEEE, and local codes. ¥ Pay particular attention to the requirements for motor and power disconnect devices, emergency stop pushbuttons, pre-start alarms and guards on mechanical power transmission apparatus. ¥ Make sure motor selected is appropriately sized for the application. Follow the recommendations in Section 2 of this manual, Pre-Installation. ¥ If you configure the drive to operate above 60 Hz, the motor may operate above its nameplate speed. Personal injury or equipment damage may exist when you operate the motor and driven machines above their rated speed. Make certain that all guards and shields are in place before operating at any speed. Refer to the motor manufacturer to verify safe motor speed. Before operating the equipment, make sure that appropriate guards and safety devices are in place.

Warning

Large frame AF93/IS903 Adjustable Frequency Drives may require more than one person to move from one location to another. Observe proper lifting techniques to avoid injury when handling heavy electrical equipment.

AF93/IS903 Instruction Manual 2-4

Pre-Installation INSTALLATION

Where to Locate Drive Consider the following: 1. Locate the drive in an area consistent with the environment specifications listed in the Specifications section of this manual. Mount enclosures away from heavy and overhead construction.

3. Refer to the illustrations in the Drawings section of this manual for the mounting dimensions of each enclosure. 4. Make sure there is plenty of ventilating space surrounding the drive. Refer to the illustrations in the Drawings section of this manual for ventilation clearances.

2. Select the type of enclosure that meets your application. Note: Standard AF93/IS903 NEMA 1 drives can withstand an ambient temperature of 122¡F (50¡C) up to 3,300 feet (1000 meters) above sea level. Standard AF93/IS903 NEMA 12 drives can withstand an ambient temperature of 104¡F (40¡C) up to 3,300 feet (1000 meters) above sea level. If you install the drive in an optional enclosure, the maximum temperature is derated. If you install an enclosure at temperatures exceeding these values, you must derate the unit as follows: For every 9¡F (5¡C) over the rated temperature you must derate the AF93/IS903 current ratings by 10%. However, do not exceed a maximum of 131¡F (55¡C) under any circumstances. In addition for every 1000 feet (300 meters) above the rated altitude, you must derate the AF93/IS903 current ratings by 2%.

AF93/IS903 Instruction Manual 2-5

Pre-Installation INSTALLATION

Application Considerations When you plan your AF93/IS903 Adjustable Frequency Drive installation, consider its application. Different applications, such as industrial process control and HVAC system control, require different drive options, motors and software configuration.

3. An AF93/IS903 circuit breaker is a lockable means for disconnecting the motor from the power source. The circuit breaker is mounted in an optional NEMA 1 or 12 enclosure or MCC.

The following is a list of items you should keep in mind when you plan the installation and order the materials. It is important to note that some of the options available for your drive must be installed at the factory.

AF93/IS903 Options 1. Remember you must have an input line impedance of at least 1% and not over 5% for proper drive operation. You should calculate the input line impedance to determine whether a 1% input reactor is required. Refer to the discussion on Input Line Considerations later in this section for more details on determining input line impedance. 2. Order a 3% or 5% input line reactor to correct input line harmonic distortions as required. Refer to the discussion on Input Line Characteristics on later in this section for more details for more details on harmonic distortions.

AF93/IS903 Instruction Manual 2-6

Pre-Installation INSTALLATION

Application Considerations 3. Multiple motors may be operated by an AF93/IS903 drive if:

Motor Selection Careful consideration of the proper motor is essential to obtain optimum performance from your drive. Contact your Cutler-Hammer sales representative or distributor for additional assistance and/or literature regarding motor selection and other aspects of drive applications. 1. Your AF93/IS903 drive is designed to be connected directly to a single, NEMA design B, three phase AC motor. The motor must be selected and applied so that the average operating motor current and horsepower do not exceed the continuous current and horsepower ratings of the drive. The intermittent operating current must not exceed the intermittent current rating of the drive. 2. Consider the effect of speed on the cooling capacity of the motor. As you slow down some types of motors (such as a Totally Enclosed Fan Cooled [TEFC]), its internal fan turns slower which reduces air flow through the motor. Typically, these types of motors may overheat if you operate them for extended periods of time at their rated torque and a reduced speed (less than 50% of full speed). Choose a motor that matches the expected duty, torque range and speed.

¥ Total current from all motors does not exceed the current rating of the AF93/IS903. ¥ Individual motor overload protection is supplied. ¥ All motors must start and change speed together.

!

Warning

If you configure the drive to operate above 60 Hz, the motor may operate above its nameplate speed. Personal injury or equipment damage may exist when you operate the motor and driven machines above their rated speed. Make certain that all guards and shields are in place before operating at any speed. Refer to the motor manufacturer to verify safe motor speed.

AF93/IS903 Instruction Manual 2-7

Pre-Installation INSTALLATION

Input Line Considerations All wiring must comply with the requirements of the National Electric Code (NEC) and/or other codes as required by the authority having jurisdiction over the installation. The installer must ensure that the electrical connections at the site conform with the connection diagrams shipped with the drive. Note: Make sure you use the most recent version of the codes when you install your AF93/IS903 drive.

Input Line Conductor and Branch Circuit Overload Protection Selection Use a combination of the following guidelines to choose the correct input line conductors and proper branch circuit overload protection: Note: Select the input line conductor size and branch circuit overload protection in accordance with applicable code requirements. ¥ The input line and branch circuit overload protection must be rated for the input voltage and current stated on the nameplate of the drive. ¥ For runs over 300 feet, consider the recommended minimum wire size listed in Table 2-1. ¥ In addition, consider the wire size capacity of the input line terminals: 2 to 10 Hp Maximum wire size is #10 AWG 15 to 25 Hp Maximum wire size is #4 AWG ¥ The input line conductors must be made of copper with a temperature rating of at least 167¡F (75¡C).

Grounding Connections For personal safety and reliable equipment operation, firmly connect each chassis to earth ground as shown in the connection diagrams in the Drawings section of this manual. The AF93/IS903 chassis ground conductor should be the same size as the input line conductors or sized according to electrical code requirements. Use a copper or aluminum conductor. Connection to a grounded conduit does not provide an adequate equipment ground. Make sure that all operatorÕs control stations and motor frames are adequately grounded.

Input Line Impedance You must ensure that the input line power has an impedance of at least 1% and less than or equal to 5% equated to drive size for proper operation. Damage to the drive may occur if the source impedance is less than 1%. If the source impedance is more than 5%, the drive may not provide rated output voltage. Actual input current varies considerably in response to the efficiency and power factor of the motor connected to your drive and the impedance of the power source. Since power source impedance has an effect on the harmonic content of the input current, the amount of impedance affects the value of the input line current.

¥ The power terminal tightening torque range is 16-18 in. lbs. on terminals L1, L2, L3, T1, T2, T3, and the ground lugs.

AF93/IS903 Instruction Manual 2-8

Pre-Installation INSTALLATION

Input Line Considerations The value of source impedance is expressed as a percent of the effective impedance of the drive. To determine the source impedance as a percent of the effective impedance of the drive, you must know: ¥ The short circuit capacity of the power source at the driveÕs input power terminals. ¥ The full load (output) current rating of the drive (found on the nameplate). The following calculation provides the source impedance as a percent of the effective impedance of the drive: Full Load Current 100 = Source Short Circuit Capacity * Impedance

The short circuit capacity must be at least 20 times the full load current rating (5% impedance) and no more than 100 times the full load current rating (1% impedance). For example, if the full load (output) current of an AF93/IS903 drive is 22 amps and the short circuit current capacity of the power source is 2200 amps, the source impedance is: 22 2200

* 100 = 1.00%

Since the design of a power distribution system often includes a short circuit capacity study, power distribution system drawings or other distribution system documentation may show the short circuit capacity at various points. If this data is not available, contact your CutlerHammer sales representative or distributor for help on estimating or calculating short circuit current capacity.

Pre-Installation INSTALLATION

Input Line Considerations Harmonic Distortion As stated in the discussion on Input Line Impedance, source impedance can affect the harmonic content of the input line current. As source impedance increases, line current harmonic content decreases. The relationship between input line impedance and harmonic voltage distortion is just the opposite of the relationship between impedance and current distortion. As source impedance increases, so does harmonic voltage distortion.

For example, if the source impedance (expressed as a percent of the effective impedance of the drive) is 1%, you will cause less than 5% harmonic voltage distortion when you connect a single AF93/IS903 to an undistorted power source. If the source impedance increases to 5%, the resulting harmonic distortion is less than 10%. Contact your Cutler-Hammer sales representative or distributor for assistance in estimating harmonic distortion in multiple drive installations. They can also provide assistance in selecting a means of harmonic reduction such as line reactors.

AF93/IS903 Instruction Manual 2-11

Pre-Installation INSTALLATION

Input Line Considerations Input Line Routing For 7.5 to 25 Hp AF93/IS903: ¥ If you use conduit - Use a separate conduit for input line conductors and output power conductors. Never route analog and digital wiring from any equipment in the same conduit as input or output power wiring. ¥ If you use cable trays - Use a separate cable tray for input line conductors and output line conductors. Never route analog and digital wiring from any equipment in the same cable tray as input or output power wiring. For 2 to 5 Hp AF93/IS903: If you use conduit, use separate conduit for input and output power and AF93/IS903 control wiring, up to the AF93/IS903 drive. At the drive use a T-coupling to combine the input power and output power wiring and attach to conduit entry point.

Multiple Conductor Wiring If multiconductor wiring is used, a separate multiconductor cable must be used for the input line wiring for each drive.

Line Fuses Line fuses are intended to remove input line voltage from the drive in the event of internal component and drive failure. Line fuses must not be used in place of branch circuit overload protection.

CT (Current Transformer) On 2 Hp, 3 Hp, and 5 Hp units manufactured prior to May 2, 1996 and 7.5 and 10 Hp units manufactured prior to July 1, 1996, a CT was supplied internal to the drive for ground fault protection. On units manufactured after these dates, the ground fault protection is built into the transistor module. If your drive contains a CT to provide ground fault protection, input lines L1,

L2, and L3 must pass through the CT when you are installing the input lines (See 5 and 10 Hp connection drawings): 1. Remove the foam packing. 2. Pass L1, L2, and L3 through the knockout and current transformer and then connect them to terminals L1, L2, and L3, respectively. 3. DO NOT pass any ground lines through the current transformer. 4. The current transformer is connected to the logic board at the factory.

AF93/IS903 Circuit Breaker This option is used as a mechanical means of disconnecting output power to the motor. AF93/IS903 circuit breakers must not be used in place of branch circuit overload protection.

Isolation Transformers Isolation transformers can be used with AF93/IS903 Adjustable Frequency Drives. Remember that the input line impedance must be at least 1% and not over 5% with the drive running. See the previous discussion on Input Line Impedance.

Power Factor Correction The displacement power factor at the input terminals of an AF93/IS903 drive is approximately 0.95 at all operating speeds and loads. Therefore, power factor correction capacitors are not required and should not be installed. If capacitors for correcting the power factor of other equipment are installed too close to the drive, there may be an undesirable interaction between the capacitors and the drive.

Standby Power Generation Three phase standby power generators can be used with AF93/IS903 Adjustable Frequency Drives as long as the input line impedance is within the 1% to 5% range.

AF93/IS903 Instruction Manual 2-12

Pre-Installation INSTALLATION

Output Power Considerations To comply with local and nationally recognized codes, such as the NEC, you must consider proper output power wiring when you plan your Adjustable Frequency Drive installation. Note: Make sure you use the most recent version of the codes when you install your AF93/IS903 drive.

Output Power Conductor and Ground Conductor Sizing Use a combination of the following guidelines to choose the correct output line conductors and proper branch circuit overload protection: Note: Select the output power conductor size in accordance with applicable code requirements. ¥ The output power conductors must be rated for the output voltage and current stated on the nameplate of the drive. ¥ For runs over 300 feet, consider the recommended minimum wire size listed in Table 2-1. ¥ In addition, consider the wire size capacity of the output line terminals: 2 to 10 Hp Maximum wire size is #10 AWG 15 to 25 Hp Maximum wire size is #4 AWG ¥ The input line conductors must be made of copper with a temperature rating of at least 167¡F (75¡C). ¥ The power terminal tightening torque range is 16-18 in. lbs. on terminals L1, L2, L3, T1, T2, T3, and the ground lugs. ¥ The AF93/IS903 chassis ground conductor should be the same size as the output line conductors or sized according to electrical code requirements. Use a copper or aluminum conductor. ¥ Connection to a grounded conduit does not provide an adequate equipment ground.

Output Power Conductor Routing For 7.5 to 25 Hp AF93/IS903: ¥ If you use conduit - Use a separate conduit for input line conductors and output power conductors. Never route analog and digital wiring from any equipment in the same conduit as input or output power wiring. ¥ If you use cable trays - Use a separate cable tray for input line conductors and output line conductors. Never route analog and digital wiring from any equipment in the same cable tray as input or output power wiring. For 2 to 5 Hp AF93/IS903: If you use conduit, use separate conduit for input and output power and AF93/IS903 control wiring, up to the AF93/IS903 drive. At the drive use a T-coupling to combine the input power and output power wiring and attach to conduit entry point.

Overcurrent Protection AF93/IS903 Adjustable Frequency Drives are designed to automatically provide overcurrent protection for the output power circuit only if one motor is connected to the drive and sized to match the drive. If more than one motor is connected to the drive, each motor must have its own overcurrent protection. In addition, the combined input current rating on the nameplate of each motor must not exceed the output current rating of the drive.

Power Factor Correction Power factor correction capacitors must never be connected to the output of the drive. They may damage the drive and would not serve any useful purpose.

¥ Make sure that all operatorÕs control stations and motor frames are adequately grounded.

AF93/IS903 Instruction Manual 2-13

Pre-Installation INSTALLATION

Analog and Digital Signal Considerations To comply with the design of the drive and local and nationally recognized codes, consider proper analog and digital signal wiring when you plan your Adjustable Frequency Drive installation. Note: Make sure you use the most recent version of the codes when you install your AF93/IS903 drive.

External Fault Signal Some configurations, such as an optional overload interlock relay, provide an external fault signal to the drive so the drive will not start if the relay has tripped and has not been reset. If this or other option that requires an external fault signal is installed by the factory, the signal is factory wired. See the connection diagrams in the Drawings section of this manual for details.

Analog and Digital Signal Wiring ¥ 18 AWG wire size is recommended. Minimum wire size is 20 AWG. Maximum wire size is 16 AWG. ¥ One conductor per terminal for 16 AWG conductors. Two conductors per terminal at 18 AWG. Three conductors per terminal at 20 AWG. ¥ Maximum length is 500 feet; call your CutlerHammer sales representative or distributor for longer runs. ¥ Use shielded cable for the analog signal conductors where indicated on the terminal block connection diagram. Typically, shielding is required for all analog input and output runs. All digital signal runs over 75 feet long should be shielded. ¥ Only ground the shield conductor of shielded cable at the terminal block of the drive for input signals only. Output signals should not be grounded at the drive end of the cable but should be grounded at the device.

AF93/IS903 Instruction 2-14

¥ The analog and digital signal conductors must be made of copper with a temperature rating of at least 167¡F (75¡C).

Analog and Digital Conductor Routing For 7.5 to 25 Hp AF93/IS903: ¥ If you use conduit: Never route analog and digital wiring from any equipment in the same conduit as input or output power wiring. Do not run AF93/IS903 Adjustable Frequency Drive analog and digital signal conductors in the same conduit that has control wiring for other equipment. For 2 to 5 Hp AF93/IS903: If you use conduit, use separate conduit for input and output power and AF93/IS903 control wiring, up to the AF93/IS903 drive. At the drive use a T-coupling to combine the input power and output power wiring and attach to conduit entry point. ¥ If you use cable trays: Never route analog and digital wiring from any equipment in the same cable tray as input or output power wiring. Separate analog and digital wiring for your AF93/IS903 drive from other control equipment wiring using a metal tray divider or keeping the conductors at least 2 inches apart. Trays containing analog and digital wiring should be separated from trays containing low voltage (up to 30 volts) power wiring by at least 9 inches. Trays containing analog and digital wiring should be separated from trays containing medium voltage (between 30 and 150 volts) power wiring by at least 18 inches.

Specifications INSTALLATION

General Specifications !

Caution

It is your responsibility to check your installation to make sure it meets the conditions stated in these specifications before you install your Adjustable Frequency Drive. Operation of the drive outside of these specifications will void your warranty.

Frequency Range 1.7 to 180 Hz You must make certain that the motor and associated equipment are capable of operating safely, and that protective guards are in place, before you operate your drive above 60 Hz.

Input Line Conditions ¥ Three phase 240 VAC, three phase 480 VAC, or single phase 240 VAC (±10 %). ¥ Input line impedance - 1% to 5%. You must purchase a 1% input line reactor if you calculate or measure input line impedance less than 1%. ¥ Line Distortion - The harmonic voltage distortion of the input power line should be limited to 10% or less including distortion caused by the drive(s). (See IEEE Standard 519.)

¥ Drive insensitive to line phase sequence. ¥ Suitable for use on a circuit capable of delivering not more than 65K RMS symmetrical amperes, 480 volts maximum.

Input Line Transients ¥ Drive protected and operational for line transients to ANSI C62.41 (formerly IEEE 587) and IEC 801. ¥ Drive protected (but may trip) for severe or prolonged transients per IEEE 446.

Operator Interface The AF93/IS903 operator interface consists of: ¥ An LCD display (two rows of 16 characters per row) and keypad. ¥ Operator can display operating conditions, parameter settings, or English language diagnostic messages on the LCD. ¥ Operator can change the settings of a predefined list of parameters. ¥ Operator can issue Start, Stop, Forward, and Reverse commands and change speeds using the keypad. Keypad can also be set for remote Start and speed change.

¥ Input phase voltage unbalance less than 3% (per IEEE Standard 446). ¥ Single phase input protection - drive will safely run on single phase until input current rating of the drive is exceeded. The output current rating must be derated by 50% for all drives except the 2 Hp, 240 VAC unit (AF93AG0B002D) when single phase 240 V power is supplied. The 2 Hp, 240 VAC unit is fully rated for single phase or three phase application.

8

STOP

Digital Input Stop/Run Enable Command. Must be LO (or connected to terminal 7) for drive to start or run; acts as a Run Enable. Momentary HI (or opening) stops the drive. Active in both KEYPAD and REMOTE modes. To run the drive in KEYPAD mode, a customer supplied jumper must be placed between terminals 7 and 8, and terminals 7 and 15. Attempting to start in KEYPAD mode without the jumper installation will yield a RUN DISABLED message. If drive is in AUTO RESTART mode, LOHI (closed-open) transition exits the auto restart sequence and enters STOP mode without asserting a fault. If drive is in FAULT mode, LO- HI (closed-open) transition resets the fault and stops the drive.

9

START

Digital Start Input. In 3-wire control, a momentary contact between terminals 9 and 7 sends a RUN command to the drive. In 2-wire control, a jumper is installed between terminals 9 and 7.

About Your Keypad SECTION 3 The function for each keypad button and indicator is described on this page. The sections listed in italics have the detailed procedures for using the features of your keypad. The item numbers in parenthesis refer to the illustration of the keypad on the next page. Run Indicator (item 1) - This green indicator is on steady while running, accelerating, or decelerating due to a speed reference change. This indicator is flashing while the drive is searching for the motor speed during Start Into Spinning Motor, while waiting to accelerate during flux build-up of the motor, during deceleration due to a Stop command, while waiting to auto-restart during power-up or after a trip, and while DC braking. This applies whether the motor is running as a result of a Start or Jog command. Fault Indicator (item 2) - This red indicator is lit (and the Run indicator goes out) if your drive is in the FAULT mode. See the Troubleshooting Your Drive section of this manual for the procedure on listing fault messages on your keypad display. Forward Indicator (item 3) - This yellow indicator is on steady when the drive is operating in a forward direction or a Forward command is present and the drive is stopped. This indicator is flashing when a Forward command is present and the drive is operating in a reverse direction. Reverse Indicator (item 4) - This yellow indicator is on steady when the drive is operating in a reverse direction or a Reverse command is present and the drive is stopped. This indicator is flashing when a Reverse command is present and the drive is operating in a forward direction. F/R (Forward/Reverse Button) (item 5) - Use this button to toggle between Forward and Reverse. This operation can be disabled via a software parameter (see Section 4, Using the Parameters, for more information). Start Button (item 6) - Use this button to set the drive in the RUN mode and start the drive ramp to the current speed setting. Pressing this button in the FAULT mode clears the fault condition and immediately restarts the drive to ramp to the set speed. Stop Button (item 7) - Use this button to set the drive in the STOP mode and start the ramp to zero speed (unless the Stop Profile parameter is set to coast, in which case the motor will coast to a stop).

Stop Button, continued: Pressing this button in the FAULT mode clears the fault condition and leaves the drive in the READY mode, but does not restart the drive. If the drive is in the REMOTE mode, pressing this button stops the drive at the specified deceleration rate. To restart the drive, you must cycle the external start contact with the stop contact closed (3-wire control), or cycle the stop contact with the start contact closed (2-wire control). Up and Down Buttons (item 8) - These buttons allow you to scroll through the parameters in the SCROLL mode or change parameter data in the CHANGE SETTINGS mode. With the drive in KEYPAD and RUN mode, pressing either the Up or the Down button will make the drive immediately jump to the CHANGE SETTINGS mode and begin adjusting the Speed Setpoint. Select Button (item 9) - Use this button to toggle between LOCAL (Keypad) or REMOTE (Remote Station) operating modes. This operation can be disabled via a software parameter (see Section 4, Using the Parameters, for more information). Remote Indicator (item 10) - This yellow indicator shows the drive is in the REMOTE mode. In this mode, commands can only be issued from a remote source. Keypad Indicator (item 11) - This yellow indicator shows the drive is in the KEYPAD mode. In this mode, commands can only be issued from the keypad. Operate Button (item 12) - Press this button to place the LCD in the OPERATE mode. In this mode, Operation Display Parameters are shown on the LCD. (See Section 4, Using Your Parameters, for a discussion on Operation Display Parameters). Operate Indicator (item 13) - This indicator is lit when the LCD is in the OPERATE mode and the LCD displays Operation Display Parameters. (See Section 4, Using Your Parameters, for a discussion on Operation Display Parameters).

Keypad Tips and Modes SECTION 3 Tips on Using Your Keypad Keep the following points in mind when you use the keypad: ¥ If you press more than one button at a time, the drive will not respond. ¥ In most cases, the keypad issues a command when you press a button, and the command stays active when you release it. When you press the button, hold it down for a moment before you release it so the drive has time to respond to the command. ¥ Two minutes after you issue the last command from the keypad, the LCD will return to the OPERATE mode. ¥ If the Fault indicator comes on, refer to the Troubleshooting Your Drive section for the procedure for displaying a fault message on your LCD.

Operate, Scroll, and Change Settings Modes The AF93/IS903 drive has three keypad conditions: OPERATE, SCROLL, and CHANGE SETTINGS. In the OPERATE mode, the LCD displays two Operation Display Parameters showing current information on items such as Speed and Load. Use the ÒUpper DisplayÓ and ÒLower DisplayÓ parameters to select which Operation Display Parameters appear during the OPERATE mode (see Section 4, Using the Parameters, for more information). In the SCROLL mode, the Up and Down buttons scroll through the parameters displayed on the LCD. In the CHANGE SETTINGS mode, the parameter values described in Section 4, Using the Parameters, can be changed.

AF93/IS903 Parameter List USING THE PARAMETERS

AF93/IS903 Parameter List Legend Parameter Number Each parameter is numbered and the list presents the parameters in the same order they are displayed when you scroll them on the LCD (using the Up or Down buttons in the SCROLL mode). Indexing by parameter number makes it easy to find information on each parameter as you use your AF93/IS903 drive.

Parameter (LCD Display) This column provides the full description of each parameter and its LCD display (mnemonic). The LCD Display appears within the parenthesis below each parameter name. This display appears on the upper line of the LCD when you are in the SETUP mode and are changing the parameter settings. The current setting of the parameter appears on the lower line of the LCD.

Note that instead of an analog value, some of the parameters, such as digital and analog outputs, provide a list of functions or conditions on the lower line of the LCD to choose from. These are noted with quotation marks (Ò Ó) in the Range of Adjustment column. When you set the value for a digital or analog output parameter, you choose the condition that will cause the relay contact to close (for RELAY 1 or 2) or for the analog voltage to be output (ANALOG OUTPUT #1 or #2).

Notes This column provides specific information about using the parameter. Note that many parameters list Run Locked in this column. This means that you cannot change the settings for this parameter while the RUN indicator is lit.

Factory Setting Range of Adjustment This column provides the range of values you can choose from when you change the setting of a parameter. When the drive is in the CHANGE SETTINGS mode, use the Up or Down buttons to change the parameter data (numeric and alpha data) that appears on the lower line of the LCD.

This is the value set at the factory for the parameter.

Customer Setting Space is provided for you to write in the value for each parameter for your AF93/IS903. Photocopy this list and keep it handy so you can update your current setting as you customize your drive.

Some of the ranges depend upon the value you have set for another parameter. For example, the range of SPEED SETPOINT is ÒMinimum Speed to Maximum Speed.Ó This means that the range for this parameter starts at the value of MINIMUM SPEED and extends to the value of MAXIMUM SPEED.

Remote Function Specifications Parameter Number: 23 Mnemonic: REMOTE FUNCTION Range of Adjustment: ÒSPEED FOLLOWERÓ or ÒPI REGULATORÓ or ÒANALOG LOAD LIMÓ or ÒDIGITAL POTÓ Run Locked?: Yes Factory Setting: ÒSPEED FOLLOWERÓ When your drive is in REMOTE mode, speed is controlled by one of the these Remote Functions: ÒSPEED FOLLOWERÓ, ÒPI REGULATORÓ, ÒANALOG LOAD LIMÓ or ÒDIGITAL POTÓ. A discussion about the priority interaction among the various signals that can control the motor speed follows the discussion of each type of remote function. ÒSPEED FOLLOWERÓ - You can vary the speed setpoint using a current or voltage speed follower input. The speed follower input can be connected as follows: ¥ If the signal is 4-20 mA, connect it to terminals 1 and 2. ¥ If the signal is 0-10 VDC, connect it to terminals 2 and 3. ¥ If the signal comes from a potentiometer, connect it to terminals 2, 3, and 4. ¥ If the signal is 0-5 VDC, and the output impedance of the signal follower is less than or equal to 250 ½ and can output 20 mA, connect the signal to terminals 1 and 2. ÒPI REGULATORÓ - You can automatically maintain a reference setpoint using the ÒPI REGULATORÓ option. This option incorporates a feedback signal and reference setpoint. The following connections are required: Setpoint - 0-10 VDC, connect it to terminals 2 and 3 (terminal 3 is +) or connect potentiometer to terminals 2, 3, and 4.

Feedback - 4-20 mA connected to terminals 1 and 2. A 0-5 VDC signal can also be connected to these terminals if the output impedance of the transducer is less than or equal to 250 ½ and it can output 20 mA. PI Regulator Feedback - The feedback signal is calibrated to provide constant information on whether the motor is actually running faster or slower than the setpoint. If the motor is running faster than setpoint, the drive reduces the frequency and if the motor is running slower than setpoint, the drive increases the frequency. Integral and Proportional Gain - In simple terms, the Integral Gain parameter controls how quickly the drive responds to information provided by the feedback signal and the Proportional Gain parameter controls how close to the target value the system will maintain control. It takes some trial and error in setting these parameters since some applications have a natural tendency to favor tight control and others may start to quickly oscillate around the target speed the tighter you try to maintain control. PI Regulator Application Example - PI is a closed loop control system consisting of a set point, a process variable, and an error signal which will control the drive output. Typical applications include wet well level control, temperature or pressure control, or flow rate control. PI control starts with a PI Setpoint adjusted by a remote signal input, such as a potentiometer. The drive compares the setpoint to a process variable signal, PI Feedback, and creates an error signal. The error signal is processed to create the speed reference for the drive. In the example shown in Figure 4-1, a pressure transducer provides a 4-20 mA signal that corresponds to the duct pressure. The drive will control the speed of the blower to maintain the desired duct pressure regardless of the amount of air flow being supplied through the duct.

AF93/IS903 Instruction Manual 4-18

AF93/IS903 Parameter Descriptions USING THE PARAMETERS

Remote Function (Cont.) Since the PI Regulator software works best when the analog feedback is scaled to the full range, we recommend that the Minimum Analog Reference (parameter 8) be set to 0% and the Maximum Analog Reference (parameter 9) be set to 100% (for direct acting control). In applications that require inverse control, set the Minimum Analog Reference parameter to 100% and the Maximum Analog Reference parameter to 0%. Using ÒMIN POT REFÓ and ÒMAX POT REFÓ, the operating band can be adjusted for the specific application. In this example for a desired setpoint of 10 psi and a maximum range of 8 to 12 psi, the operator would set Minimum Potentiometer Reference and Maximum Potentiometer Reference to the equivalent percentages of these values.

We recommend that, for most applications, you set the initial value of the Integral Gain (parameter 24) to 10000 and Proportional Gain (parameter 25) to 10000. Since these values are not Run Locked (can be changed while the system is running) you can adjust them (in 1000 unit intervals) while you observe its operation. To increase or decrease the response time to changes in feedback value, you might want to change the value of Integral Gain. To control the amount of under and overshoot, you might want to adjust the Proportional Gain. Note that some types of systems, such as HVAC control, might not need much proportional gain.

AF93/IS903 Parameter Descriptions USING THE PARAMETERS

Remote Function (Cont.) ÒANALOG LOAD LIMÓ - This function combines a speed follower with an external method of controlling the load limit: Speed Follower - 4-20 mA connected to terminals 1 and 2. A 0-5 VDC signal can also be connected to these terminals if the output impedance of the transducer is less than or equal to 250 ½ and it can output 20 mA. Load Limit Control - 0-10 VDC, connect it to terminals 2 and 3. Connect potentiometer to terminals 2, 3, and 4. This function allows you to control the load limit and speed from a remote station in situations where you expect wide variations in the load. Note that ÒANALOG LOAD LIMÓ is capped by ÒLOAD LIMITÓ (parameter 22). Remember, when the load limit you set is exceeded, the drive will go into foldback and reduce speed to try to prevent further overload. The lower you set the load limit, the lower the speed will be when the drive goes into foldback. If the load limit control does not prevent an overload, the drive will shut down. ÒDIGITAL POTÓ - This function sets up a ÒpotentiometerÓ that allows you to smoothly increase or decrease motor speed at a remote station. If you connect terminals 13 and 7, the speed increases at the rate established by Accel Time (parameter 11) or Accel Time 2 (parameter 14). When you disconnect terminal 13 from 7, the speed stops increasing and remains constant (drive ignores terminal 11, Jog). If you connect terminals 14 and 7, the speed decreases at the rate established by Decel Time (parameter 12) or Decel Time 2 (parameter 15). When you disconnect terminal 14 from 7, the speed stops decreasing and remains constant (drive ignores terminal 11, Jog). If both 13 and 14 are connected to 7 the speed decreases at a rate established by the appropriate deceleration time.

The POT WPR (terminal 3) is used to set the load limit while in DIGITAL POT mode. If a load limit control potentiometer is not used to control torque, a jumper must be installed between terminals 3 and 4.

Priority Interaction in REMOTE Mode There is a priority scheme that the drive uses to establish the speed setpoint in the REMOTE mode: Priority 1 (Lowest Priority) - 0-10 VDC Speed Follower Priority 2 - 4-20 mA Speed Follower (If Signal exceeds 1 mA) Priority 3 - PI Regulator Priority 4 - Terminals 12, 13, or 14 closed to terminal 7 (Preset Speeds or Digital Potentiometer) ¥ If you use SPEED FOLLOWER, a current source greater than 1 mA will override a voltage source. ¥ If you use SPEED FOLLOWER, a voltage source will override a current source less than 1 mA. ¥ If you connect terminal 12, 13, or 14 to terminal 7, Preset Speeds will override SPEED FOLLOWER. ¥ If you use PI REGULATOR, Preset Speeds will override the speed established by PI REGULATOR. ¥ If you use ANALOG LOAD LIM, Preset Speeds will override the speed follower connected to terminals 1 and 2. ¥ You cannot override speed set by DIGITAL POT, except by load limit. ¥ The load limit you set (using parameter 22 or 23) will fold back the speed setpoint when the load limit is exceeded.

AF93/IS903 Instruction Manual 4-20

AF93/IS903 Parameter Descriptions USING THE PARAMETERS Note that if you use DIGITAL POT (Remote Function (parameter 23)), the drive ignores terminal 12 and Preset Speeds are not used to set the speed setpoint.

where ÒxÓ is a value of 1 to 3

Range of Adjustment: Minimum Speed to Maximum Speed Run Locked?: No Factory Setting: 0 These parameters set jump speeds which are used to avoid operating at speeds that create problems with mechanical resonance. The jump speeds, combined with Jump Width (parameter 37), create frequency windows. The drive can accelerate or decelerate smoothly through the windows, but will not stop at any frequency within a window. Jump frequency windows are illustrated in the graph shown below.

This parameter defines how long in seconds that DC injection braking lasts. When DC current is injected into the windings of an induction motor, the motor acts as a brake. Approximately 20% braking torque is injected for the period of time set by this parameter when the motor speed drops below 5 Hz.

Number of Restart Attempts Before Lockout Specifications Parameter Number: 43 Mnemonic: RESTART ATTEMPTS Range of Adjustment: 0 to 255 Run Locked?: Yes Factory Setting: 0 This parameter defines the number of times the drive will attempt to restart after a trip. If this number is exceeded, the drive faults and the appropriate fault designation is shown on the LCD. Entering 0 disables auto restart. The restart counter is reset every 60 minutes.

Time Between Restart Attempts

Parameter Number: 45 Mnemonic: STOP PROFILE Range of Adjustment: ÒCOASTÓ or ÒRAMPÓ Run Locked?: No Factory Setting: ÒRAMPÓ This parameter allows you to choose whether the motor will coast to a stop or ramp down to a stop per the appropriate deceleration time and profile.

Load Inertia Specifications Parameter Number: 46 Mnemonic: LOAD INERTIA Range of Adjustment: 0 to 100 Run Locked?: Yes Factory Setting: 20 This parameter adjusts the internal speed regulator based on the inertia of the load. For higher inertia loads, the user should set this parameterÕs value higher. When tuning this parameter, it is most practical to change the setting in increments of 10 to 20 units. The value Ò20Ó is intended to equal 2 times connected inertia.

Parameter Number: 48 Mnemonic: SELECT KEY Range of Adjustment: ÒDISABLEÓ or ÒENABLEÓ Run Locked?: Yes Factory Setting: ÒENABLEÓ

Parameter Number: 51 Mnemonic: SPINNING MOTOR Range of Adjustment: ÒDISABLEÓ or ÒENABLEÓ

This parameter allows you to disable the Select button and lock the drive into REMOTE or KEYPAD operation.

Efficiency Optimization Specifications Parameter Number: 49 Mnemonic: EFFICIENCY OPT Range of Adjustment: ÒENABLEÓ or ÒDISABLEÓ Run Locked?: No Factory Setting: ÒDISABLEÓ Selecting ÒENABLEÓ makes the motor run more efficiently by reducing flux in the motor for centrifugal loads, but reduces the motorÕs ability to change load quickly. Use ÒENABLEÓ whenever possible (i.e., unless motor stalls) to save energy.

Power Up Restart Specifications Parameter Number: 50 Mnemonic: ÒPOWER UP RESTARTÓ Range of Adjustment: ÒDISABLEÓ or ÒENABLEÓ Run Locked?: No Factory Setting: ÒDISABLEÓ

Run Locked?: Factory Setting:

This parameter should be disabled when you run multiple motors from the same drive. If this parameter is enabled, the drive will search for the speed of the motor in the commanded direction. If the speed is not found, the drive will search in the opposite direction of the commanded direction. If the speed is still not found, the drive will assume the motor is at rest and initiate a normal start. Therefore, a 1 to 3 second delay in start time will occur when the Start Into Spinning Motor parameter is enabled. If only one motor is connected to the drive, you can enable the parameter so the drive ÒcatchesÓ the load at the speed it is running and ramps it to the last speed command issued by the drive. If the motor is turning in the reverse direction to the last command sent by the drive, the drive will ÒcatchÓ the motor, ramp it down to 0 Hz, and ramp it up to the speed and direction last commanded by the drive.

Selecting ÒENABLEÓ makes the drive restart after waiting the period of time set in Parameter 44 (RESTART DELAY) if power is applied in the REMOTE mode with the Start and Stop/Run Enable inputs closed. Selecting ÒDISABLEÓ requires a transition on the Start or Stop/Run Enable inputs for the drive to restart.

Checking DC Bus Voltage TROUBLESHOOTING Step 1. Set a digital volt meter to read DC volts, and use the 0 to 1000V scale. Step 2. Connect the digital volt meter between the ÒAÓ and ÒBÓ terminals of the capacitor assembly as shown in Fig. 5-1. Step 3. Monitor the bus voltage until it reaches zero volts DC.

!

Danger High Voltage

Internal parts of the drive are at line voltage when AC power is connected to input terminals. This voltage is extremely dangerous and can cause death or serious injury. When the supply is disconnected from the input terminal block, it will take up to 10 minutes before the DC bus capacitors are discharged to a safe voltage. To ensure the voltage is safe, monitor the capacitor discharge with a digital voltmeter connected between the ÒAÓ and ÒBÓ terminals on the capacitor assembly as described. Do not work on the drive until the capacitors have completely discharged. Do not attempt to discharge the capacitors by short circuiting the bus.
