r50047[2]: Actual Delta Ia [in A]
r50047[3]: Lowest Delta-Ia up until now since the last firing pulse [in A]

(r50072[1]).
r50047[0]: Decision criterion (= 3)
r50047[1]: Number of Delta-Ua, that Ua may still be away from the EMF

r50047[5]: Actual armature firing angle [in degrees]
r50047[6]: Actual EMF in [in V]
r50047[7]: Actual Ia sample value [in A]
4:
A SINAMICS DCM connected in parallel has detected a commutation failure or overcurrent.
r50047[0]: Decision criterion (= 4)
5:
Test command was entered via p51583.
r50047[0]: Decision criterion (= 5)
r50047[1]: Actual voltage CD [in V]
r50047[2]: Actual armature firing angle [in degrees]
r50047[3]: Actual EMF in [in V]
r50047[4]: Actual Ia sample value [in A]
r50047[5]: Actual torque direction (0, 1 or 2)
Remedy: Acknowledge the fault and switch off /switch on the drive
F60320 (N, A) CCP not functional
Message value: %1
Message class: General drive fault (19)
Drive object: DC_CTRL
Reaction: OFF2 (NONE, OFF1, OFF3)
Acknowledge: IMMEDIATELY
Cause: The SIMOREG CCP is not functional.
Possible fault causes:
- Hardware defect in the charge circuit of the turn-off capacitors.
- Fuse failure in the armature circuit, line side or motor side.
- Fuse failure in the pre-charging circuit for the chopper capacitors.
- Chopper resistors still cooling down (this is necessary)
Fault value (r0949, interpret decimal):
1: No voltage at the U, V, W connections of the SIMOREG CCP.
2: The voltage at C-D at the SIMOREG CCP does not match the voltage C-D at the SINAMICS DCM.
3: The turn-off capacitors of the SIMOREG CCP have not reached the setpoint voltage.
4: No connection between SINAMICS DCM (X165_2, fast pulse inhibit interface) and SIMOREG CCP (X165).
5: No connection between SINAMICS DCM (X177) and SIMOREG CCP (X172) via the serial interface.
6: No connection between several SIMOREG CCPs (X29_PAR or X30_PAR, turn-off pulse interface).
7: SIMOREG CCP data invalid or not available (r51570, r51571, r51572).
11: The I2t value (r51575) of the voltage limiting chopper 1 is too high (> 100 %).
12: The I2t value (r51576) of the voltage limiting chopper 2 is too high (> 100 %).
20: The chopper capacitors were not able to be pre-charged within the time set in p50089.
