Special Precautions Use your inverter only within ambient temperature variations.  –10°C to +40°C Because the life of the inverter is greatly affected by ambient temperature, do not use it outside the specification. Also, pay attention to the installation direction's and conditions. (See page 10.) Do not attempt insulation testing between the inverter cables. To measure the insulation resistance of the power supply cables or the motor  cables, disconnect them from the inverter. Never conduct insulation testing on the control circuits. (However, insulation testing can be performed between the charging unit and the ground.) Never touch the inside of the inverter during operation. This is extremely dangerous the inverter contains high-voltage circuitry. Be sure to wait at least 5 minutes after the inverter has been turned off, before making an internal check. Do not touch the aluminum diecast heat fins as they become hot during operation. Radio interference The main circuit of the inverter contains a harmonic component and may interfere with communications equipment such as AM radios if these are used nearby. The amount of radio interference depends on the field strength in the area where the inverter is used. While it is difficult to completely eliminate radio interference, it may be reduced by changing the angle of your radio antenna, using a noise filter with the inverter, housing the inverter in a metallic shield box, or routing inverter cables in metal conduit. If a magnetic contactor is connected to the power supply side of the inverter, never use it to start or stop the motor (inverter). Switching the inverter on and off frequently by a magnetic contactor in the primary side, can cause the inverter to malfunction. Do not turn the inverter load on and off during operation as this causes inverter fault trips. Turn the inverter on and off only by means of its operation signals.

8

The inverter will be damaged if the power supply voltage is applied to its output terminals. Applying power to the U, V or W output terminal will damage the inverter. Check for miswiring of  power and control circuit of the application system. Never apply a voltage that exceeds the voltage limitations of the inverter.

Power supply voltage

Do not connect a power factor correction capacitor or suppressor to the output terminal of the inverter. Such devices can damage the inverter, its capacitors and other  parts. Remove the device if one is connected.

Inverter

Phase advance capacitor  Induction motor 

Do not use the inverter to drive any load (voltage regulator, electromagnet, etc.) other than a motor.

Single-phase motors cannot be used with the inverter.

Precautions regarding inverter's protection function Various protection functions, such as stall prevention, current limiting and overcurrent protection, are incorporated in the inverter. These protection functions are used to protect the inverter from unexpected faults that could occur during use of the inverter, and are not the control functions normally used. Thus, during normal usage, avoid applications that activate these protection functions. Depending on the state, the inverter life could drop, or damage could occur. Before using the inverter, measure the output current, etc., with a measuring instrument, and check the details of the fault trip memory. Make sure that there are no problems in respect to the all precautions listed in the instruction manual and in respect to the product specifications.

Installation ！ ● ● ● ● ●

●

ATTENTION

Install the unit on a non-combustible material such as metal. Installing it on other material could lead to fire. Do not place the unit near flammable materials. Doing so could lead to fire. Do not hold the cover during transportation. Doing so could cause the unit to drop and lead to injuries. Do not allow foreign matter such as metal swarf enter the unit. Entry of this type of matter could lead to damage and/or fire. Mount the unit according to the instruction manual in a place where the weight can be withstood. Failure to do so could lead to dropping of the unit and to injuries. Do not install or operate an inverter that is damaged or with parts missing. Doing so could lead to injury.

Install the inverter vertically. Installing it in any other way decreases its radiative effect and results in malfunction.

Make sure the ambient temperature stays within the specification. The ambient temperature surrounding the inverter will increase when it is installed near a heating unit or housed inside a panel. This may reduce the life of the inverter. If  you want to house the inverter inside a panel, give careful consideration to the cooling method and panel size. ● Ambient temperature variations °

Note: Ambient temperatures should be measured at a point 5 cm from the inverter. ● Space around the inverter

ATTENTION

ATTENTION

Do not connect an AC power supply to the output terminals (U/T 1, V/T2, W/T3). Doing so could lead to injury or fire. Confirm that the product's rated voltage and the AC power supply voltage match. Failure to do so could lead to injury or fire. Do not connect a braking resistor other than the braking resistor designated by MEW (exclusive option) to the braking resistor terminals (DB+. DB–). Doing so could lead to fire. Tighten the terminal screws to the designated tightening torque. Failure to do so could lead to overheating or fire.

■ Precautions

Note the following points carefully to prevent miswiring and misuse of the inverter. 1. Connect the power supply to input terminals (R/L 1, S/L2, T/L3) and the motor to output terminals (U/T 1, V/T2, W/T3). 2. Do not connect anything other than the optional brake resistor across terminals DB+ and DB– (5.5, 7.5, 11kW). Never short these terminals to each other as this will damage the internal electronics of the inverter. 3. Use sleeved crimp terminal lugs for power supply and motor  connections. 4. After terminating power cables double check for tightness as access will be limited once control circuit wiring is in place. 5. When connecting the inverter directly to a large-capacity transformer  (500 kVA or more), be sure to use the optional power factor correcting reactor in the input circuit of the inverter. 6. Select peripheral devices and wire size according to the table on page 19.

Drive control inputs are high impedence, low voltage and as such the use of good quality relay/push-buttons is recommended as current drawn by these terminals is low. No-voltage contact signal or opencollector outputs signal should be used with control terminals. 10 to 16. (If a voltage signal is applied across these terminals, the internal electronics may be damaged.) ＊ Input circuit schematics are shown on right. Take special care to avoid loop or leakage current. When an inductive load is to be driven by an open-collector output, be sure to use a freewheel diode.

ATTENTION

The motor speed/torque characteristics could change significantly and the motor may suddenly start or stop when data is being changed during operation. (before making changes please be sure of the cause and effect that these may have on the drive/machine, ensure personal safety at all times.) Failure to do so could lead to injury. [Parameters that can be changed during operation] Parameter No. 1/2 : 1st acceleration/deceleration time Parameter No. 5/44 : DC boost level/2nd DC Boost level Parameter No. 27 ~ 29 : Jog frequency, acceleration/deceleration time Parameter No. 30 ~ 36 : Preset frequency 2 ~ 8 (Note 3) Parameter No. 37 ~ 42 : Acceleration/deceleration time 2 ~ 4 Parameter No. 57/58 : Bias/Gain frequency (Note 3) Parameter No. 59 : 0 – 5V output voltage compensation Parameter No. 61 : Line speed multiplier  Parameter No. 64 : Carrier frequency Drive output may go "0 volt" output and the rotation of the motor shaft may stop if "0000" is set in any of the pre-set speed settings 2 ~ 8, "0 Hz or less is set for the bias frequency" or "0000 is set for the gain frequency". When making changes to the above data be aware of the possible cause and effect it may have on the motor and machine with personnel safety in mind.

In that case, after  the details of the trip are confirmed and measures are taken, resetting can be done with this SW signal. • Always input the SW signal at "closed". • Even if the stop signal is input during a fault trip, the trip state will be held. • Confirm the details of the trip and take measures, and then reset the state by "opening" this SW signal. [Jogging function] The signal input terminal is set for executing jog function from external connection. [Auxiliary stop input] The signal input terminal is set for fault stop or coast-to-stop from source other than the inverter. [Frequency setting signal switching] The signal input terminal is set to select between the potentiometer signal and voltage/current signal, to be switched when the frequency setting signal is input from an external source.

Switching between Manual and Automatic Frequency Setting Signal ●

When inputting the frequency setting signal from an external source, it can be switched easily between a "potentiometer signal (manual)" and "voltage/ current signal (automatic)" by using a switch. This is effective for feeding back the frequency setting signal as a voltage/ current signal from a sensor (temperature, pressure) and switching to the manual frequency setting potentiometer signal and automatic control signal required for the "adjustment, inspection and forced control" required when automatically controlling the inverter such as for fan and pump applications.

If the V/F pattern is set to FF, the V/F pattern will be determined according to the maximum output frequency and base frequency.

Notes) 1. A frequency exceeding the upper frequency clamp (parameter No.55) cannot be output. 2. If a general purpose motor with a rated frequency of 50 or 60Hz is run at a higher  frequency, the motor may be damaged. Always set the frequency to match the motor  characteristics. 3. If the base frequency must be changed together with the maximum output frequency for a high-speed exclusive motor, etc., change parameter No.16 with the procedure given above. 4. If the general purpose motor is to be run with a frequency higher than the commercial frequency, set the base frequency to the normal motor rated frequency (50 or 60Hz). 5. The motor will enter the rated output characteristics, and the generated torque will drop in inverse proportion to the frequency when above the base frequency (normally 50 or  60Hz).

Setting Maximum Output Voltage ●

Maximum output voltage at the base frequency can be programmed with Parameter 62. When the power supply voltage fluctuation is too large or the power supply voltage exceeds the motor's rated voltage, set maximum output voltage below the power supply voltage to stabilize the output voltage. (This function is disabled (000) by factory setting, so maximum output voltage equals supply voltage).

Maintenance and Inspection (Precautions) ！

ATTENTION

● Wait at least five minutes after turning the input power OFF before starting inspection.

(Also confirm that the CHARGE lamp has gone out.) Failure to do so could lead to electric shocks. ● Maintenance, inspection and part replacement must be done by qualified persons.

(Remove all metal personal belongings (watches, bracelets, etc.) before starting the work.) (Use tools treated with insulation.) Failure to do so could lead to electric shocks or injuries. ● Never modify the unit. Doing so could lead to electric shocks or injuries.

(It would also invalidate the warranty).

！

ATTENTION

● Have an electrician periodically tighten the terminal screws.

Loosening of the terminal screws could lead to overheating or fire.

Precautions for inspections When measuring the insulation between the power supply line and motor line, always disconnect the wires connected to the inverter first. Do not perform a megger test on the control circuit.

The inverter is mainly configured of semiconductor elements. Thus, daily inspections must be carried out to prevent the effect of the working environment such as the temperature, humidity, dust and vibration, and to prevent other trouble that occurs due to the passage of part usage and part life. The standard replacement years that apply when the inverter is used a general environment (ambient average annual temperature 30°C, load rate of 80% or less, and 12 working hours or  less a day) are given on the next page.

72

Inspection items (1) Daily inspection Check that the inverter is operating as intended. Check the input and output voltages of the inverter during operation using a voltmeter. (2) Periodic inspection Check all locations where inspection can only be performed when the inverter is stopped.

Parts replacement The lifetime is greatly dependent on the installation conditions. For example: a) The lifetime of a relay depends on the wear condition of its contact surfaces. The contact current and load inductance are major factors. b) The capacitor inside the inverter is used mainly as a smoothing filter and its lif etime varies greatly with temperature as internal chemical reactions take place. An aluminum electrolytic capacitor has Arrhenius law characteristics (10°C doubling law); the lifetime is 50% when the temperature rises 10°C, or the lifetime is 200% when the temperature is reduced 10°C. The lifetime of the inverter is therefore determined by temperature. If the inverter is used at high temperatures, the aluminum electrolytic capacitor may wear  out even though other parts remain normal. In this case, the aluminum electrolytic capacitor must be replaced to keep the inverter working.
