G00

Advanced CUD left

Advanced CUD in left-hand slot.
In addition to the connections and functions of the standard CUD, the Advanced CUD has two DRIVE-CLiQ connections and one option slot. The use of an Advanced CUD also provides the opportunity of inserting an additional CUD (Standard or Advanced) to increase the computational performance and the number of terminals. For example, this can be used to implement additional technological functions.
By using an Advanced CUD, which is located in the left-hand slot instead of the standard CUD, the SINAMICS SMC30, TM15, TM31 and CBE20 components can be connected to the SINAMICS DC MASTER.

G10

Standard CUD right

Standard CUD in the right-hand slot (precondition for option G00).
Selecting option G10 provides the possibility of further increasing the performance of technological functions for the SINAMICS DC MASTER. As a result of the additional standard CUD that is inserted in the right-hand slot of the electronics tray, users have additional computational performance at their fingertips in order to fulfill even the highest demands when it comes to closed-loop control performance.

G11

Advanced CUD right

Advanced CUD in the right-hand slot (precondition for option G00).
With option G11, users can address the highest demands regarding the closed-loop control performance and use the wide range of interfaces. With this option, in addition to the Advanced CUD located in the left-hand slot, an additional Advanced CUD can be mounted in the right-hand slot. This therefore doubles the number of interfaces of the SINAMICS DC MASTER.

G20

Communication Board CBE20 left

CBE20 PROFINET left-hand side (precondition for option G00).
The Communication Board CBE20 allows a connection to be established to a PROFINET?IO network via the Advanced CUD.

The SINAMICS DC MASTER then assumes the function of a PROFINET IO device in the sense of PROFINET and offers the following functions:

• PROFINET IO Device
• 100 Mbit/s full duplex
• Supports real-time classes of PROFINET IO:
• RT (Real-Time)
• Connection to control systems as PROFINET IO devices in accordance with PROFIdrive, Specification V4.1.
• In addition to PROFIBUS (standard), PROFINET can also be used for engineering with the STARTER commissioning tool.
• Integrated 4-port switch with four RJ45 sockets based on the PROFINET ASIC ERTEC400. The optimum topology (line, star, tree) can therefore be configured without additional external switches.
• The SINAMICS Link function can be used in conjunction with option S01 or S02 (memory card).

The CBE20 is inserted in the option slot of the Advanced CUD, which is inserted in the left-hand slot.

The cable is available as cable sold by the meter.

G21

Communication Board CBE20 right

CBE20 PROFINET right-hand side (possible with option G11).
With option G21, an Advanced CUD can be inserted in the righthand slot, which is used to expand CBE20. More detailed information on the functionality, selection and ordering data of the CBE20 is provided under option G20.

Further, this field power section has an integrated field overvoltage protection function. This option cannot be ordered for units with rated DC currents from 15 to 30 A.

L21

Unit fan for single-phase connection

Converter units from 400 A up to and including 1 200 A rated DC current can, using this option, be equipped with a fan for connection to a single-phase supply. This is supplied from the internally generated 230 V AC control voltage, and from a circuit perspective, is treated in exactly the same way as a standard fan. Cabinet fans, which are installed in the converter cabinet in order to implement higher degrees of protection, are not affected by the option. The fans are protected using an integrated overtemperature protection function.

L85

85 A field power section

All components in the field circuit and the field power section in the SINAMICS DC MASTER are dimensioned for a rated current of 85 A (possible for units with a rated DC current, armature ? 1 500 A; also in conjunction with option L11 (field power section 2Q)).

Coated PCBs

(only involves modules of the SINAMICS DC MASTER DC Converter)

In order to improve the reliability for increased degrees of pollution and climatic stress, it is possible to order modules of the SINAMICS DC MASTER that are coated on both sides by specifying option M08.
The AOP30 as well as the Sensor Modules and Terminal Modules have coated PCBs as standard.

M10

Nickel-plated copper busbars

Nickel-plated copper busbars are used, which means that an increased degree of availability can be achieved in aggressive atmospheres. Cabinets with rated current of 1 500, 1 600, 1 900, 2 000 and 2 200 A have aluminum busbars as standard. Nickel-plated copper busbars can also be supplied by specifying option M10.

• Performing an offline long-time trace.
• Download the DCC block library into the drive.
• Update the firmware.

The SINAMICS Link function requires that the memory card is always inserted.

S02

Memory card right

With option S02, users receive a memory card for one Standard CUD or one Advanced CUD, which is inserted in the right-hand slot. This option is only possible, if one of the options G10 or G11 is ordered for installing a CUD in the right-hand slot.

L04

Armature supply with extra-low voltage 10 to 50 V

With option L04, the SINAMICS DC MASTER Cabinet is re-equipped for operation with 10 to 50 V AC. This is frequently required especially for electrochemical applications, when controlling solenoids, when using the converter to supply the fields of special motors or Ward-Leonard converters (MG sets).

Note:

This option can only be selected for units with rated supply voltages of up to 575 V. The commutating reactor is omitted (option L22), and on the plant or system side, a converter transformer is required for the armature circuit. In this case, it is not possible to order option L00 (radio interference suppression filter).

V60

Rated line frequency 60 Hz

This option must be specified if the line frequency of the armature and auxiliary circuits is 60 Hz instead of the standard 50 Hz. The commutating reactors for the armature circuit and the field circuit as well as the motor protection circuit breaker of the unit fan (for units with ? 400 A rated DC current) are then appropriately adapted.

Y02

Matching transformer for the field supply

This option can be selected if the 3?phase AC auxiliary supply deviates from 400 V 50 Hz or 460 V 60 Hz, or if the field voltage is to be adapted to the actual motor field voltage. The required secondary voltage of the adaptation transformer and the rated field current must be specified in plain text. The adaptation transformer is, up to a primary voltage of  500 V 3 AC, implemented as autotransformer. For certain option combinations, this option can result in increased cabinet dimensions.

Y03

3 AC auxiliary voltage not available

This option should be selected if a 3-phase auxiliary power supply is not available. In this case, the auxiliary power supply is taken from inside the cabinet in front of the main armature switch of the armature circuit.

Note:

Option L22 (no armature commutating reactor) cannot be selected at the same time as this option! The rated input voltage must be specified.

Y04

3 AC auxiliary voltage not the same as the standard voltage

As standard, the cabinet should be supplied with a 400 V 3 AC, 50 Hz auxiliary voltage, with clockwise rotating field, TN or TT supply system, grounded transformer neutral point. When selecting option V60 (rated line frequency of 60 Hz) this auxiliary voltage must be 460 V 3 AC.
Option Y04 should be selected if the 3-phase AC auxiliary voltage deviates from these values, or if an IT line supply or grounded main conductor is being used. The required voltage must be specified in plain text. The auxiliary voltage must not exceed 690 V. The auxiliary power supply must be protected against short-circuit and overload on the plant side. Data for the fuses for the auxiliary power supply (supplies) should be taken from the type and order-specific circuit diagram.

Depending on the particular version, it may be necessary to additionally select options Y01 and/or Y02.

OFF functions

B30

Interlocking option for infeed circuit breaker

An external interlocking option (terminals to integrate an external NC contact) is provided so that the infeed circuit breaker or main contactor can be externally opened. For instance, this can be a leading auxiliary contact of a circuit breaker on the line side, so that an overvoltage occurring when switching off the transformer on the primary side cannot be propagated to the SINAMICS DC MASTER. An EMERGENCY STOP must be simultaneously issued; terminals are provided as standard for this function. An internally generated 230 V AC control voltage is available at the terminals; an isolated contact should be externally connected.

L57

The function includes interrupting the power feed for the converter (armature circuit and field circuit) via the line contactor or circuit breaker and bypassing the microprocessor controller using a safety combination according to EN 60204-1. The motor then coasts down. It must be carefully ensured that an abrupt switch off does not represent any risk or potential danger.

L59

EMERGENCY STOP Category 1 for controlled stopping in accordance with EN 60204-1

The function includes shutting down the drive via a fast stop along a deceleration ramp to be parameterized by the user. The power feed to the DC converter is then interrupted as described for EMERGENCY OFF Category 0.

The PT100 evaluation unit can monitor up to three sensors. The sensors can be connected in a two- or three-wire system. With the two-wire system, inputs xT1 and xT3 must be assigned. With the three-wire system, input xT2 must also be connected (x = 1, 2, 3). The limit values can be freely programmed for each channel. Shielded signal cables are recommended. If this is not possible, the sensor cables should have at least have twisted-pair wires.

Unused channels can be suppressed via parameters.

The output relays are integrated in the internal fault and alarm circuit of the drive cabinet. Customers can access the signals via two freely assignable signaling relays.

The power supply for the PT100 evaluation unit and the evaluation are realized in the converter.

B83

Overvoltage protection

A SICROWBAR AC overvoltage protection device is installed to protect the power semiconductors and is connected to the armature voltage supply. Overvoltages that occur on the AC side of converters are mainly caused by switching operations when disconnecting from the line supply at the transformer primary. This applies both to operational switching operations (shutdown at no-load) as well as in the case of a fault (shutdown under load).

Mode of operation:
If an overvoltage occurs, which reaches the response voltage of the integrated firing module, then the break-over diodes trigger and in turn trigger their associated thyristors. As a consequence, the varistors are switched to the line supply. The varistors absorb the overvoltage energy. An RC protective circuit protects the thyristors against an excessively steep voltage rate of rise when the current is interrupted. Details on the overvoltage protection device are described in Catalog D 23.1.

Note:

A supplementary cabinet is required with this option, 400 mm or 600 mm wide. The delivery time and installation altitude above 2 000 m for this option are available on request.

Monitoring functions

L52

ARC detector (arcing detector)

A sensor is installed to monitor the cabinet system for any arcing. Here, light sensors inside the cabinet senses any arcing and if arcing is detected, the system is shut down with an Emergency Stop; the main contactor or supply circuit breaker are opened.

Note:

A 24 V DC power supply is required (option L06, L07 or L09).

L82

Fault current monitoring in the grounded line supplies (TN or TT supply systems)

An electronic differential relay monitors the fault current in the armature circuit with respect to ground (PE). If a ground fault occurs, then the "Ground fault" signal is issued. The drive is simultaneously switched off. This option only includes monitoring the armature circuit, the fault current monitoring for the auxiliary circuit must be realized on the plant side.

Note:

For protection using a differential current monitor for shutdown, the protective conductor or PEN conductor of the cables for the cabinet supply and motor armature circuit are dimensioned according to DIN VDE 0100, Part 540. Main conductor cross-section according to DIN VDE 0160. As a consequence, generally the cable cross-section can be reduced.

L84

PTC evaluation device for alarm and fault for two sensors

This option includes a thermistor motor protection device (with PTB approval) for PTC temperature sensors (PTC thermistors, type A) for alarm and trip. The power supply for the thermistor motor protection device is realized in the cabinet.

L87

Insulation monitoring in non-grounded line supplies (IT system) with insulating monitoring devices from the Bender company

An insulation monitor is used to monitor the armature circuit (three-phase and DC connections). If a ground fault occurs, this is signaled using a signal lamp (yellow) and the "Earth leakage" signal at a terminal. An additional coupling device is used for rated supply voltages above 690 V 3 AC.

Notes:

• For protection using insulation monitoring in non-grounded line supplies, potential bonding is required for the cabinet and motor as well as the conductive parts that can be simultaneously touched. Protective conductor cross-section according to DIN VDE 0100, Part 540. Main conductor cross-section according to DIN VDE 0160. When the main switch/circuit breaker is closed, external ground faults, which occur in the line supply outside the converter system, are also detected and signaled by the ground fault monitoring in the drive cabinet. Insulation monitor settings should be made during commissioning.
• The auxiliary power supply in the basic version is not influenced by this option. The auxiliary power supply must be provided from a grounded line supply. Other versions are possible on request.
• As soon as the first fault is detected by the insulation monitor, the converter system must be brought to a safe state if a second ground fault cannot be ruled out. The system is not permitted to be switched on again until the ground fault has been eliminated. Background: If a second fault occurs, protective separation cannot be ensured in all cases.

L88

Insulation monitoring in non-grounded line supplies (IT system) with insulating monitoring devices from the AREVA company

An insulation monitor is used to monitor the armature circuit (three-phase and DC connections). If a ground fault occurs, this is signaled using a signal lamp (yellow) and the "Earth leakage" signal at a terminal. An additional coupling device is used for rated supply voltages above 690 V 3 AC.

Notes:

• For protection using insulation monitoring in non-grounded line supplies, potential bonding is required for the cabinet and motor as well as the conductive parts that can be simultaneously touched. Protective conductor cross-section according to DIN VDE 0100, Part 540. Main conductor cross-section according to DIN VDE 0160. When the main switch/circuit breaker is closed, external ground faults, which occur in the line supply outside the converter system, are also detected and signaled by the ground fault monitoring in the drive cabinet. Insulation monitor settings should be made during commissioning.
• The auxiliary power supply in the basic version is not influenced by this option. The auxiliary power supply must be provided from a grounded line supply. Other versions are possible on request.
• As soon as the first fault is detected by the insulation monitor, the converter system must be brought to a safe state if a second ground fault cannot be ruled out. The system is not permitted to be switched on again until the ground fault has been eliminated. Background: If a second fault occurs, protective separation cannot be ensured in all cases.

L90

CCP (Converter Commutation Protector)

The Converter Commutation Protector SIMOREG CCP is used to protect line-commutated SINAMICS DC MASTER converters in inverter operation against inverter commutation faults. SIMOREG CCP limits the current that flows when inverter commutation faults occur to a non-hazardous value so that the thyristors and the associated super-fast fuses are protected.

For line-commutated inverters, an appropriate line-side counter voltage is required in order to commutate the current between the individual power semiconductors. Commutation can be prevented from being completed (commutation fault) as a result of uncontrolled switching operations, line supply dips (weak line supplies, thunderstorms, etc.). As a result, in the regenerative feedback direction, a high current flows through the line supply or a cross-current in the converter. This can result in fuses blowing or under certain circumstances can destroy the semiconductors.

The firmware of the SINAMICS DC MASTER identifies if inverter commutation faults are pending and then issues the command to turn off the power semiconductors in the converter to the SIMOREG CCP. SIMOREG CCP then turns off the power semiconductors, ensures that the conditions to reduce the current in the motor are present and absorbs the magnetic energy stored in the motor as electric energy.

Benefits:
This eliminates the complex and time consuming replacement of fuses after inverter commutation faults.

Although inverter commutation faults cannot be prevented, their effects can be.

• Gearboxes and the driven machine are protected by shutting off the current in time before it reaches its possible maximum value in the case of a fault therefore protecting them against inadmissibly high torque surges.
• For high rated system currents, high-speed DC circuit-breakers were used up until now to protect the fuses against rupture. By using the CCP, protection is now cost-effectively possible even for lower line currents, whereby SIMOREG CCP has the following advantages when compared to high-speed DC circuit-breakers even at high current levels:
  
  • Protection also for circulating currents
  • Lower system costs
  • Lower space requirements
  • No additional air reactor to reduce the current rate-of-rise when a fault occurs
  • Lower operating costs, as it requires no maintenance
  • High degree of availability

Additional information for commissioning and the function of the SIMOREG CCP can be taken from the operating manual and Catalog D 23.1.

Note:

The option must be accommodated in an additional cabinet section; depending on the SIMOREG CCP required, the converter cabinet becomes significantly wider.
For installation altitudes above 1 000 m, with this option, on request, the transport and storage temperature should not fall below –25 °C.
In order to be able to assign the matching SIMOREG CCP for the option, when ordering, the following data must be provided:

• Line supply voltage and power section
• Required undervoltage range of the power section
• Rated motor armature voltage
• Rated motor current
• Details on the required overcurrent where necessary (magnitude, cycle duration)
• Inductance of the load (motor, cable plus if required, a smoothing reactor)

L99

Monitoring the temperature inside the drive cabinet

The temperature is monitored in two stages. The response temperature for the alarm is 5 °C below the fault message threshold. This is oriented to the overload capability of the converter and results in the drive being shut down. The fault message can be deselected by making the appropriate parameter settings.

K50

Sensor Module Cabinet-Mounted SMC30

The CUD of the SINAMICS DC MASTER can already evaluate the signals of an incremental encoder. For applications where more than one encoder must be evaluated, either a second CUD and/or Sensor Module Cabinet-Mounted SMC30 can be used. The SMC30 can be used to evaluate SSI encoders with incremental signals, which for instance, are used for positioning functions. Encoders, which have a DRIVE-CLiQ interface, cannot be evaluated at the SINAMICS DC MASTER or at the SMC30. These encoders are generally not used in DC drive technology.

The following encoder signals can be evaluated:

• Incremental encoders TTL/HTL with and without wire break detection (wire break detection is only available with bipolar signals)
• SSI encoder with TTL/HTL incremental signals
• SSI encoder without incremental signals

The motor temperature input, available on the SMC30, is not evaluated for SINAMICS DC MASTER. A motor temperature sensor can be evaluated using the temperature measurement input provided on each CUD.

1) Twisted pair and shielded signal cables.

Note:

For this option, an Advanced CUD with DRIVE-CLiQ port (G00, G11) and a 24 V DC power supply (L06, L07 or L09) are required.
