SINAMICS alarms
230061 <location>Bypass contactor monitoring
Message value: Fault cause: %1 bin
Drive object: AFE_SINUMERIK_828, BIC_SINUMERIK_828, SERVO_COMBI, SERVO_SINUMERIK828, SIC_COMBI,
SIC_SINUMERIK_828
Reaction: OFF2 (NONE, OFF1)
Acknowledge: IMMEDIATELY (POWER ON)
Cause: At the end of the monitoring time (p0255[1]), the actual state of the bypass contactor does not match the desired state.
Fault value (r0949, interpret bitwise binary):
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.
230062 <location>Bypass contactor has been opened under current
Message value: -
Drive object: AFE_SINUMERIK_828, BIC_SINUMERIK_828, SERVO_COMBI, SERVO_SINUMERIK828, SIC_COMBI,
SIC_SINUMERIK_828
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.
230070 <location>Cycle requested by the power unit module not supported
Message value: %1
Drive object: AFE_SINUMERIK_828, BIC_SINUMERIK_828, SERVO_COMBI, SERVO_SINUMERIK828, SIC_COMBI,
SIC_SINUMERIK_828
Reaction: OFF2
Acknowledge: IMMEDIATELY
Cause: A cycle is requested that is not supported by the power unit.
Fault value (r0949, interpret hexadecimal):
0: The current control cycle is not supported.
1: The DRIVE-CLiQ cycle is not supported.
2: Internal timing problem (clearance between RX and TX instants too low).
3: Internal timing problem (TX instant too early).
Remedy: The power unit only supports the following cycles:
62.5 µs, 125 µs, 250 µs and 500 µs
Re fault value = 0:
Set a permitted current control cycle.
Re fault value = 1:
Set a permitted DRIVE-CLiQ cycle.
Re fault value = 2, 3:
Contact the manufacturer (you may have an incompatible firmware version).
