Safety information

2

WARNING Note safety information Operating the equipment without taking the safety information into consideration can result in property damage, serious injury, and even death. You must not operate the converter without taking this safety information into consideration. This document is to be regarded as an integrated whole along with the "General Manual". Therefore, you must pay particular attention to the safety information provided in the "Safety information" chapter of the "Closed-Loop Control Manual" and the "General Manual".

2.1

General product-related safety information Note In addition to the safety information provided here, you must also comply with the safety information provided in the section of the same name in the "General Equipment Manual".

Safety-relevant information WARNING Correct usage Improper use of the devices described here can result in damage to property, serious injury and even death. Therefore, please adhere strictly to all instructions for proper usage. Operating modes, overload conditions, load cycles and ambient conditions different from those described in this document are allowed only in exceptional circumstances and only by special arrangement with the manufacturer.

Siemens AG Manual 2.01 6SL385 03.09.2009

Safety information 2.2 Notes on operator protection

2.2

Notes on operator protection Note In addition to the safety information provided here, you must also comply with the safety information provided in the section of the same name in the "General Equipment Manual".

The five safety rules The five safety rules must be observed. 1. Disconnect the system. 2. Protect against reconnection. 3. Make sure that the equipment is de-energized. 4. Ground and short-circuit. 5. Cover or enclose adjacent components that are still live.

Safety-related information for working on the converter DANGER Dangerous parts Depending on their degree of protection, converters can have live, and possibly moving or rotating, parts during operation. There is a risk of death or severe injury/material damage if the required covers are removed or if the converter is used or operated incorrectly. Always take the appropriate precautions before touching any components.

12

Siemens AG Manual 2.01 6SL38503.09.2009

Safety information 2.3 Electromagnetic fields

High voltages DANGER Dangerous high voltages High voltages can cause death or serious injury if the safety rules are not observed or if the equipment is handled incorrectly. When this equipment is in operation, very high voltages occur and can be still present for quite some time after the equipment has been shut down or for as long as the motor is still rotating. Make sure that work is only carried out by qualified personnel under due observance of the five safety rules, the warning information in this documentation and the safety information on the product itself.

Hot surfaces CAUTION High temperatures If the converter is not in operation, the anti-condensation heating is activated when the limit value of the temperature control is reached. Once activated, the anti-condensation heating can generate a great deal of heat. Serious injury (scalding) may occur if you come into contact with these components.

2.3

Electromagnetic fields WARNING Electromagnetic fields "electro smog" Electromagnetic fields are generated by the operation of electrical power engineering installations such as transformers, converters or motors. Electromagnetic fields can interfere with electronic devices, which could cause them to malfunction. For example, the operation of heart pacemakers can be impaired, potentially leading to damage to a person's health or even death. It is therefore forbidden for persons with heart pacemakers to enter these areas. The plant operator is responsible for taking appropriate measures (labels and hazard warnings) to adequately protect operating personnel and others against any possible risk.

Siemens AG Manual 2.01 6SL385 03.09.2009

13

Safety information 2.3 Electromagnetic fields ● Observe the relevant nationally applicable health and safety regulations. In Germany, "electromagnetic fields" are subject to regulations BGV B11 and BGR B11 stipulated by the German statutory industrial accident insurance institution. ● Display adequate hazard warning notices.

● Place barriers around hazardous areas. ● Take measures, e.g. using shields, to reduce electromagnetic fields at their source. ● Make sure that personnel are wearing the appropriate protective gear.

Switches and pushbuttons

Key-operated switch S11 Use the key-operated switch to select remote control or local operation. The position of the key-operated switch is evaluated using a TM15 terminal module. With the keyswitch position set to "Local", and once the "LOCAL/REMOTE" key has been pressed on the AOP30, priority for operation is given to the AOP30 or the starter. The AOP30 takes command. In local operation, the ON command in control word 1 and the main setpoint come from the AOP30 or the starter.

Mushroom pushbutton S100 The mushroom pushbutton is used for safety shutdown. When the safety shutdown is actuated, the converter shuts down with a fault and a corresponding message appears on the display of the operator panel. Before you restart the converter you must acknowledge the fault.

The "fast inputs" can be used in conjunction with a measuring system for position sensing. X122: To enable digital inputs (DI) 0 to 3 to function, terminal M1 must be connected. X132: To enable digital inputs (DI) 4 to 7 to function, terminal M2 must be connected. The available options are as follows: Connect the included ground reference of the digital inputs, or a bridge to terminal M (Notice: This removes isolation for these digital inputs). Note If a momentary interruption in the voltage occurs in the 24 V supply, the digital outputs will be deactivated until the interruption has been rectified.

4.4.4

Control and monitoring of the inrush circuit breaker via the internal SIMATIC S7 (option A11)

Description With this option, the internal SIMATIC S7 is used to control and monitor the inrush circuit breaker. The ON command and the OFF command of the inrush circuit breaker each go to a contactor relay. In the hardware, the "inrush circuit breaker ON command" to the contactor relay for "inrush circuit breaker ON" is interlocked with an NO contact of the contactor relay for "inrush circuit breaker OFF". From the contactor relays for "inrush circuit breaker ON", two NO contacts are routed to terminals and connected in series by means of a bridge. If necessary, the bridge can be opened, making two contacts available for "inrush circuit breaker ON". From the contactor relays for "inrush circuit breaker OFF", two NO contacts in series connection and two NC contacts in series connection are made available for "inrush circuit breaker OFF". From the back-up combination unit, one contact is made available via terminals for the undervoltage tripping. The "inrush circuit breaker OFF" feedback message also goes to a contactor relay. The OFF feedback message is required in the power unit to enable grounding switch ON.

4.4.5

Control and monitoring of the filter circuit breaker via the internal SIMATIC S7 (option A12)

Description With this option, the internal SIMATIC S7 is used to control and monitor the filter circuit breaker. In general, the filter switch is connected upstream of the circuit breaker. However, the filter switch can also be de-energized during operation. Connection during operation depends on the power supply conditions.

Redundant electronic power supply with 1 AC 230 V infeed (option K74)

Description This option can be used to supply the control cabinet electronics and the internal power supply of the power unit with an AC voltage of 1 AC 50-60Hz 100-120 V/220-240 V -15% +10%.

4.4.26

400 V 3 AC demagnetization device for output transformer for starting converters (option L30)

Description With this option, the operating point of the output transformer is drawn into the neutral zone, thus enabling undistorted transmission of the signals required for tracking.

Mode of operation This option ensures correct position tracking during operation with an output transformer. The excitation current is applied to the standing machine, and the induced voltage is measured (tracked) at the machine terminals. The exact position of the rotor is determined by the position of the three terminal voltages.

66

Siemens AG Manual 2.01 6SL38503.09.2009

Description 4.4 Description of options If a step-up transformer is positioned between the converter output and the motor, this measuring-circuit voltage is reduced in the ratio of the transformation ratio. If the magnetic characteristic curve of the step-up transformer is distorted or saturated due to prior activation, the measuring signal required for tracking may be distorted or may not be transmitted. This can result in incorrect tracking. In order to cancel the physical effect of the magnetization error, a demagnetization device is used. This demagnetization device applies a defined AC voltage to the transformer, and this AC voltage is slowly controlled to zero. This brings the operating point of the step-up transformer back into the neutral zone, thus enabling undistorted transmission of the measuring signals required for tracking. The figure shows the principal outlay of the demagnetization device, which comprises a MASTERDRIVE low-voltage converter with an output filter and a low-power step-up transformer. Except for the 400 V 3 AC infeed, the demagnetization device does not have any other customer interfaces.

Observing the five safety rules The following safety information, as well as the information provided in the "Safety information" chapter of this "Manual" and the "General Manual", must be followed for your own personal safety and to protect the equipment. WARNING Dangerous high voltage Once the converter has been switched off and while the motor is still rotating after it has been shut down due to a fault, hazardous voltages in excess of 1000 V can still be present in the converter for a long time. These voltages can result in death, serious personal injury or severe property damage. Before touching the converter, ensure that the following parts of the power unit are deenergized: • Internal busbars • Input and output terminals • Auxiliary power supply When working on the device, always observe the safety instructions on the product and the following five safety rules:

6.2

6.3

EMC (electromagnetic compatibility)

EMC-compliant cabinet installation The following section provides some basic information and guidelines that will enable you to comply with the EMC guidelines.

Cabinet installation ● Connect painted or anodized metal components using contact washers or remove the insulating layer. ● Use unpainted, de-oiled mounting plates. ● Establish a central connection between ground and the protective conductor system (ground).

Shield gaps ● Bridge shield gaps (at terminals, circuit-breakers, contactors, and so on) with minimum impedance and the greatest possible surface area. 6KLHOGEXVHV

Figure 6-1

&DEOH

7HUPLQDOV

Bridging shield gaps

Using large cross-sections ● Use ground cables and frame grounding cables with large cross-sections.

Laying the motor supply cable separately ● The distance between the motor supply cable and signal cable should be > 20 cm. Do not lay power cables and motor supply cables in parallel to each other.

Securing the potential to ground between modules with widely differing interference potential ● The operating coils for contactors and relays in the converter must be connected to overvoltage limiters (e.g. RC elements or varistors).

76

Siemens AG Manual 2.01 6SL38503.09.2009

Electrical installation 6.3 EMC (electromagnetic compatibility)

Cable installation ● Cables that are subject to or sensitive to interference should be laid as far apart from each other as possible. ● Noise immunity increases when the cables are laid close to the ground potential. For this reason, you are advised to lay these cables in corners and on the ground potential. ● Ground the reserve cores on at least one end. ● Long cables should be shortened or laid in noise resistant areas to avoid additional connecting points. ● Conductors or cables that carry signals of different classes must cross at right angles, especially if they carry sensitive signals that are subject to interference. – Class 1: unshielded cables for ≤ 60 V DC unshielded cables for ≤ 25 V AC shielded analog signal cables shielded bus and data cables operator panel interfaces, incremental/absolute encoder lines – Class 2: unshielded cables for > 60 V DC and ≤ 230 V DC unshielded cables for > 25 V AC and ≤ 230 V AC – Class 3: unshielded cables for > 230 V AC/DC and ≤ 1000 V AC/DC – Class 4: unshielded cables for AC/DC > 1000 V

Shield connection ● Shields must not be used to conduct electricity. In other words, they must not simultaneously act as neutral or PE conductors. ● Apply the shield so that it covers the greatest possible surface area. Use ground clamps, ground terminals, or ground screw connections.

Siemens AG Manual 2.01 6SL385 03.09.2009

77

Electrical installation 6.3 EMC (electromagnetic compatibility) ● Avoid extending the shield to the grounding point using a wire (pigtail) because this will reduce the effectiveness of the shield by up to 90%. ● Attach the shield to a shield bar directly after the line inlet into the cabinet. Strip the insulation of the shielded cable without interrupting the power supply and route the shield up to the device connection. 6KLHOGLQJEXV

6KLHOGHG FDEOH 0RXQWLQJFODPS

Figure 6-2

Shield connection with clip

NOTICE Incorrect connection or damaging of the shield can impair the function of the system. Handle the shield with care and make sure that it is connected correctly.

I/O interfacing ● Create a low-impedance ground connection for additional cabinets, system components, and distributed devices with the largest possible cross-section (at least 16 mm²). ● Ground unused lines at one end in the cabinet. ● Choose the greatest possible clearance between the power and signal cables (at least 20 cm). The greater the distance over which the cables are routed in parallel, the greater the clearance must be. If a sufficient clearance cannot be maintained, you must install additional shields. ● Avoid unnecessarily long cable loops.

Filtering cables ● Auxiliary voltages may have to be filtered in the cabinet to reduce incoming or outgoing disturbances.

Protective grounding Connect the protective grounding to the cabinets and components in the system via the PE conductor. Use the ground clamps for this, or the special terminal provided for the auxiliary voltage. Note The equipotential bonding conductor does not have the function of a protective conductor. It is required for safe operation and as a radio interference suppression measure. You must install the protective conductor in conformance with: ● IEC 60204-1 (DIN EN 60204-1 / VDE 0113 Part 1) Safety of machinery – Electrical equipment of machines – Part 1: General requirements. Where possible, also connect the cabinet conductively over a large area with the building ground.

Electrical installation 6.4 Connection

Signal lines, shielding CAUTION Cable installation Malfunctions can occur in the converter if cables coming from the outside are laid together with internal cables in one cable duct in the cabinet. Do not run cables coming from the outside, for example to the terminal blocks, together with internal cables in one cable duct. All signal lines must be shielded. The cable shield should be braided as cables shielded by tape or foil are five times less efficiently protected against interference. Always ground the cable shields at both ends. Contacting at one end is advantageous in exceptional cases only. You must attach the shield of incoming analog and binary cables to the shield bus at the entry point into the cabinet. Continue running the cable, still shielded, to the terminal block or board. No shields are connected to the terminal blocks or boards. Serial connecting cables must be shielded. The shield must be contacted with the metallized connector housing. It must also be connected to the shield bus. You must not connect the cable shield to a ground pin on the connector. The connector housing and front plate of the boards do not provide adequate cable shielding. You must connect the cable shields at both ends to the shield buses in the cabinets. Analog signal cables must always be shielded, regardless of whether they are installed inside or outside cabinets. In order to increase the shielding effectiveness, ground spare cores at both ends.

Grounding the cable shields at one end In the case of analog signal cables carrying small signals (mV or µA), attach the cable shield to the shield bus in the cabinet at one end. In this way you avoid ground loops and linefrequency interference. You can also connect the open shield end to the enclosure via a radio interference suppression capacitor (e.g. 0.1 µF 100 V MKT).

Contactors without suppression You must not use any contactors without suppression in the converter cabinets or in the cabinets that are connected to the converter cabinets. All contactors fitted at the factory are therefore protected by suppression circuitry. If unsuppressed contactors are installed in an adjacent cabinet, you must mutually segregate the two cabinets with a metal side plate. Contactor operating coils that are connected to the same supply network as the auxiliary power supply to the converter or are located near the converter must be protected by surge suppressors (e.g. RC elements, varistors).

Additional wiring Keep any additional wiring in the cabinet as short as possible. Route the additional wiring tightly against the cabinet housing or the mounting plates.

Description Note Function block diagram You will find a detailed explanation of the function in the function block diagram of the List Manual on the CD supplied with the converter. If the drive is to be operated in both directions of rotation or an incorrect phase sequence was connected when the cables were routed, the direction of rotation must be reversed.

Reversing the direction of rotation In order to invert the rotating field, you must swap the motor cables or specify a negative setpoint value or change the parameterization of the device.

Triggering the reversal of rotational direction Direction of rotation changeover is triggered: ● via PROFIBUS by means of control word 1, bit 11. ● via the cabinet operator panel (LOCAL mode) with the "direction of rotation changeover" key. Note Note that only one direction of rotation is enabled in the factory setting.

Functions 9.2 Setpoint channel and closed-loop control of the entire drive train. This prevents steady-state operation in their proximity, that is, although the drive can pass through this range, it must not remain within it because resonant oscillations may be excited. The suppression bandwidths allow this range to be blocked for steady-state operation. Because the points at which critical whirling speeds occur in a drive train can vary depending on age or thermal factors, a broader control range should be blocked. To ensure that the speed does not constantly increase and decrease in the suppression bandwidth (speeds), the bands are assigned a hysteresis.

Setting the minimum speed Specify a minimum speed in order to block a specific range around the stopped state for stationary operation.

Adjustable parameters You will find the necessary adjustable parameters in the Parameter Manual on the CD supplied with the converter.

9.2.1.4

Speed limitation

Description Note Function block diagram You will find a detailed explanation of the function in the function block diagrams of the List Manual on the CD supplied with the converter. Speed limitation aims to limit the maximum permissible speed of the entire drive train to protect the drive and load machine/process against damage caused by excessive speeds.

9.2.1.5

Ramp-function generator

Description Note Function block diagram You will find a detailed explanation of the function in the function block diagrams of the List Manual on the CD supplied with the converter. The ramp-function generator limits the rate at which the setpoint changes when the drive is accelerating or decelerating. This prevents excessive setpoint step changes from damaging the drive train. Two ramp function generators are available that can be selected using parameters.

Setting rounding times Additional rounding times can also be set in the lower and upper speed ranges to improve control quality and prevent load surges. Setting rounding times has the following benefits: ● It protects mechanical components, such as shafts and couplings. ● It prevents the actual speed value from being overshot when the setpoint is approached, thereby improving control quality. The ramp-up and ramp-down times each refer to the maximum speed. Note if rounding times are too long, this can cause the setpoint to be overshot if the setpoint is reduced abruptly during ramp-up. Rounding is also effective in the zero crossover; When the direction of rotation is reversed, the ramp-function generator output is reduced to zero via the initial rounding, the ramp-down time and the final rounding. Then, the newly inverted setpoint will be approached via the initial rounding, the ramp-up time and the final rounding. Rounding times that can be set separately are active in the event of a fast stop (OFF3). The actual ramp-up/ramp-down times increase with active rounding.

Adjustable parameters You will find the necessary adjustable parameters in the Parameter Manual on the CD supplied with the converter.

9.2.2.1

Properties of vector speed/torque control

Description Note Function diagram You will find a detailed description of this function in the function diagrams in the Parameter Manual. Vector control has the following properties and features: ● Stability vis-à-vis load and setpoint changes ● Short rise times with setpoint changes (→ better command behavior) ● Short settling times with load changes (→ better disturbance characteristic) ● Acceleration and braking are possible with maximum available torque ● Motor protection due to variable torque limitation in motor and regenerative mode ● Drive and braking torque controlled independently of the speed These benefits can even be achieved without speed feedback. Note Vector control can be used with or without an encoder.

9.2.2.2

Benefits of vector speed/torque control with encoder

Vector control with speed encoder An actual value speed encoder is required in the following cases: ● If a separate-field motor is used. ● When high speed accuracy is required. ● The most stringent demands on the dynamic response are required. ● Better command behavior is required. ● The shortest possible settling times are required when disturbances occur. ● Torque control in a range greater than 1:10 is required. ● A defined and/or variable torque for speeds below approx. 5 % of the rated motor frequency (p0310) must be maintained.

Monitoring, functions, and protective functions

9.3.1

Safety shutdown of the converter

Tripping of the circuit-breaker in case of undervoltage In the event of a serious fault, the converter is rapidly switched into a de-energized state by the safety shutdown function. WARNING But even with the safety shutdown function, the drive may still be running or high voltages may still be present. This can result in death, serious personal injury or severe material damage. This function cannot ensure that the drive stops immediately, nor can it ensure that residual voltages do not still exist at the output terminals and within the unit. Make sure that the drive no longer rotates and that there are no high voltages present. The shutdown of the circuit-breaker is triggered by a safety contactor combination. The circuit-breaker must be equipped with an undervoltage trip to ensure the wire-break protection for the circuit-breaker OFF command. If a circuit-breaker OFF command is issued as a result of an overvoltage trip, the circuitbreaker is switched off so that it is fail safe.

9.3.2

Potential concept

Description A noise-free connection between the internal and external supply voltage can be achieved by connecting the 0 V potentials to each other and grounding them. This also eliminates the need for the control circuit insulation monitor required by DIN EN 60204-1.

Indicating and rectifying faults

Overview The cabinet device has a number of protective functions that protect the converter from damage in the event of a fault (faults and alarms).

Indicating faults and alarms The converter indicates a fault by reporting the corresponding fault(s) and/or alarm(s) on the cabinet device operator panel. Faults are indicated by the red "FAULT" LED and a fault screen is automatically displayed. You can use the F1 Help function to call up information about the cause of the fault and how to remedy it. You can use F5 Ack. to acknowledge a stored fault. Any alarms are displayed by the yellow flashing "Signal" LED. The system also displays a note in the status bar of the operator panel, which provides information on the cause. Every fault and alarm is entered in the fault/alarm buffer along with time the error occurred and the time it was rectified. The time stamp refers to the relative system time in milliseconds (r0969).

What is a fault? A fault is a message from the converter indicating an error or other exceptional (unwanted) status. This could be caused by a fault within the converter or an external fault triggered, for example, by the winding temperature monitor for the motor. The faults are displayed and can be reported to a higher-level control system via PROFIBUS. In the factory default setting, the

Siemens AG Manual 2.01 6SL385 03.09.2009

115

Fault and system messages 11.2 Diagnostics message "converter fault" is also sent to a relay output. Once you have rectified the cause of the fault, you have to acknowledge the fault message.

What is an alarm? An alarm is the response to a fault condition identified by the converter. It does not result in the converter being switched off and does not have to be acknowledged. Alarms are "self acknowledging", that is, they are reset automatically when the cause of the alarm has been eliminated.
