4 Faults and alarms
4.2 List of faults and alarms
SINAMICS G120C
534 List Manual (LH13), 04/2014, A5E33840768B AA
A30065 (F, N) Voltage measured values not plausible
Message class: Power electronics faulted (5)
Reaction: NONE
Acknowledge: NONE
Cause: The voltage measurement supplies values that are not plausible
Bit01: Phase U.
Bit02: Phase V.
Bit03: Phase W.
Remedy: - Deactivate voltage measurement (p247.0 = 0).
- Deactivate flying restart with voltage measurement (p247.5 = 0) and deactivate fast flying restart (p1780.11 = 0).
F30071 No new actual values received from the Power Module
Message class: Internal (DRIVE-CLiQ) communication error (12)
Reaction: OFF2
Acknowledge: IMMEDIATELY
Cause: More than one actual value telegram from the power unit module has failed.
Remedy: Check the interface (adjustment and locking) to the power unit module.
F30072 Setpoints can no longer be transferred to the Power Module
Message class: Internal (DRIVE-CLiQ) communication error (12)
Reaction: OFF2
Acknowledge: IMMEDIATELY
Cause: More than one setpoint telegram was not able to be transferred to the power unit module.
Remedy: Check the interface (adjustment and locking) to the power unit module.
F30074 (A) Communication error between the Control Unit and Power Module
Message class: Internal (DRIVE-CLiQ) communication error (12)
Reaction: NONE
Acknowledge: IMMEDIATELY
Cause: Communications between the Control Unit (CU) and Power Module (PM) via the interface no longer possible. The
CU may have been withdrawn or is incorrectly inserted.
Fault value (r0949, interpret hexadecimal):
0 hex:
- a Control Unit with external 24 V supply was withdrawn from the Power Module during operation.
- with the Power Module switched off, the external 24 V supply for the Control unit was interrupted for some time.
1 hex:
The Control Unit was withdrawn from the Power Module during operation, although the encoderless safe motion
monitoring functions are enabled. This is not supported. After re-inserting the Control Unit in operation,
communications to the Power Module no longer possible.
20A hex:
The Control Unit was inserted on a Power Module, which has another code number.
20B hex:
The Control Unit was inserted on a Power Module, which although it has the same code number, has a different
serial number. The Control Unit executes an automatic warm restart to accept the new calibration data.
Remedy: For fault value = 0 and 20A hex:
Insert the Control Unit on an appropriate Power Module and continue operation. If required, carry out a POWER ON
of the Control Unit.
For fault value = 1 hex:
Carry out a POWER ON of the Control Unit.
