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.
