4.2 List of faults and alarms
A30049 Power unit: Internal fan faulty
Message value: -
Message class: Auxiliary unit faulted (20)
Drive object: B_INF, VECTOR_G
Component: Power Module Propagation: GLOBAL
Reaction: NONE
Acknowledge: NONE
Cause: The internal fan has failed.
Remedy: Check the internal fan and replace if necessary.
F30050 Power unit: 24 V supply overvoltage
Message value: -
Message class: Supply voltage fault (overvoltage) (3)
Drive object: B_INF, VECTOR_G
Component: Power Module Propagation: LOCAL
Reaction: OFF2
Acknowledge: POWER ON
Cause: The voltage monitor signals an overvoltage fault on the module.
Remedy: - check the 24 V power supply.
- replace the module if necessary.
F30051 Power unit: Motor holding brake short circuit detected
Message value: %1
Message class: External measured value / signal state outside the permissible range (16)
Drive object: VECTOR_G
Component: Power Module Propagation: GLOBAL
Reaction: OFF2
Acknowledge: IMMEDIATELY
Cause: A short-circuit at the motor holding brake terminals has been detected.
Fault value (r0949, interpret decimal):
Only for internal Siemens troubleshooting.
Remedy: - check the motor holding brake for a short-circuit.
- check the connection and cable for the motor holding brake.
F30052 EEPROM data error
Message value: %1
Message class: Hardware/software error (1)
Drive object: B_INF, VECTOR_G
Component: Power Module Propagation: LOCAL
Reaction: OFF2
Acknowledge: POWER ON
Cause: EEPROM data error of the power unit module.
Fault value (r0949, interpret decimal):
0, 2, 3, 4:
The EEPROM data read in from the power unit module are incorrect.
1:
EEPROM data is not compatible to the firmware of the power unit application.
Additional values:
Only for internal Siemens troubleshooting.
Remedy: For fault value = 0, 2, 3, 4:
Replace the power unit module or update the EEPROM data.
For fault value = 1:
The following applies for CU31x and CUA31:
Update the firmware \SIEMENS\SINAMICS\CODE\SAC\cu31xi.ufw (cua31.ufw)
