SIMOREG DC-MASTER Converter Commutation Protector Operating Instructions
7.1.6 SIMOREG DC-MASTER alarms
A030 Commutation fault or overcurrent condition has occurred
(active for operating states – –, I, II)
Possible causes
• Line voltage dip during regenerative operation
• Current control loop not optimized
A032 SIMOREG CCP not ready
(active for operating states < o4.0)
Possible causes
• Voltage not available at the connections U, V, W of the SIMOREG CCP
• Voltage at C-D at the SIMOREG CCP does not match the voltage C-D at the SIMOREG DC-MASTER
• The quenching capacitors of the SIMOREG CCP have not reached the setpoint voltage
• The parallel interface cable is not connected at the SIMOREG CCP, which is assigned the parallel switching master
• No connection between the SIMOREG DC-MASTER and SIMOREG CCP via the serial interface G-SST2
• No connection between parallel SIMOREG CCP units
• Contents of the memory of the technical data of the SIMOREG CCP (MLFB, rated values, serial number) invalid
• The I2t value of the voltage limiting chopper 1 in the SIMOREG CCP is too high (> 100 %).
• The I2t value of the voltage limiting chopper 2 in the SIMOREG CCP is too high (> 50 %).
7.1.7 SINAMICS DCM alarms
SIMOREG CCP not ready
Possible causes:
1. Voltage not available at the connections U, V, W of the SIMOREG CCP.
Trigger time: 1 s
2. Voltage at C-D at the SIMOREG CCP does not match the voltage C-D at the SINAMICS DCM.
Trigger time: 1 s
3. The quenching capacitors of the SIMOREG CCP have not reached the setpoint voltage.
Trigger time: 1 s
4. The parallel interface cable is not connected at the SIMOREG CCP which is assigned to the parallel switching master .
Trigger time: 1 s
5. No connection between the SINAMICS DCM and SIMOREG CCP via the serial interface. (The dynamic values are not
updated)
Trigger time: 1 s
6. No connection between parallel SIMOREG CCP units.
Trigger time: 1 s
7. Contents of the memory of the technical data of the SIMOREG CCP (MLFB, rated values, serial number) invalid.
Trigger time: immediately
11. The I2t value (r51575) of the voltage limiting chopper 1 is too high (> 100 %).
Trigger time: immediately
12. The I2t value (r51576) of the voltage limiting chopper 2 is too high (> 50 %).
Trigger time: immediately
A60321
20. The pre-charging of the chopper capacitors was not able to be completed within the time set in p50089 - or the condition
according to fault value 5 is fulfilled.
Trigger time: 20 ms after fault value 5 occurs
