F30052
EEPROM data error
Reaction:
NONE
Acknowledge:
POWER ON
Cause:
EEPROM data error of the power unit module.
Fault value (r0949, interpret hexadecimal):
0: The EEPROM data read in from the power unit module is inconsistent.
1: The EEPROM data is not compatible with the CU firmware.
Remedy:
Re fault value = 0:
Replace power unit module.
Re fault value = 1:
Replace power unit module.
F30053
FPGA data faulty
Reaction:
NONE
Acknowledge:
POWER ON
Cause:
Power unit module FPGA data error.
Remedy:
Replace the power unit module or update the FPGA data.
F30060 (A)
Pre-charge contactor monitoring
Reaction:
OFF2 (NONE, OFF1)
Acknowledge:
IMMEDIATELY (POWER ON)
Cause:
At the end of the monitoring time (p0255[0]), the actual state of the pre-charge contactor does not match the desired
state.
Bit 0: Monitoring time exceeded.
Bit 1: Contactor opened during operation.
Bit 2: Contactor closed in OFF state.
Remedy:
- check the monitoring time setting p0255[0].
- check the contactor wiring and activation.
- replace the contactor.
F30061 (A)
Bridging contactor monitoring
Reaction:
OFF2 (NONE, OFF1)
Acknowledge:
IMMEDIATELY (POWER ON)
Cause:
At the end of the monitoring time (p0255[1]), the actual state of the bridging contactor does not match the desired
state.
Bit 0: Monitoring time exceeded.
Bit 1: Contactor opened during operation.
Bit 2: Contactor closed in OFF state.
Remedy:
- check the monitoring time setting p0255[1].
- check the contactor wiring and activation.
- replace the contactor.
F30062 (N, A)
Bypass contactor has been opened under current
Reaction:
NONE (OFF1, OFF2)
Acknowledge:
IMMEDIATELY (POWER ON)
Cause:
The bypass contactor for the infeed has been damaged due to (multiple) opening under current.
Possible causes:
- Scheduled opening under load can be necessary to protect the converter line-up in the event of a ground fault in
high-frequency spindles.
- Operating the contactor under load can result from incorrect operation of the infeed; for example, if motoring power
is drawn from the DC link although no operating enable is present for the infeed.
Remedy:
Damaged infeeds must be replaced, to prevent serious damage to the entire converter line-up.
