SINAMICS G120 Control Units CU230P-2 Parameter Manual (LH9), 11/2009
F30012 Power unit: Temperature sensor heat sink wire breakage
Reaction: OFF1 (OFF2)
Acknowledge: IMMEDIATELY
Cause: The connection to one of the heat sink temperature sensors in the power unit is interrupted.
Fault value (r0949, interpret hexadecimal):
Bit 0: Module slot (electronics slot)
Bit 1: Air intake
Bit 2: Inverter 1
Bit 3: Inverter 2
Bit 4: Inverter 3
Bit 5: Inverter 4
Bit 6: Inverter 5
Bit 7: Inverter 6
Bit 8: Rectifier 1
Bit 9: Rectifier 2
Remedy: Contact the manufacturer.
F30013 Power unit: Temperature sensor heat sink short-circuit
Reaction: OFF1 (OFF2)
Acknowledge: IMMEDIATELY
Cause: The heat sink temperature sensor in the power unit is short-circuited.
Fault value (r0949, interpret hexadecimal):
Bit 0: Module slot (electronics slot)
Bit 1: Air intake
Bit 2: Inverter 1
Bit 3: Inverter 2
Bit 4: Inverter 3
Bit 5: Inverter 4
Bit 6: Inverter 5
Bit 7: Inverter 6
Bit 8: Rectifier 1
Bit 9: Rectifier 2
Remedy: Contact the manufacturer.
F30015 Power unit: Phase failure motor feeder cable
Reaction: OFF2 (NONE, OFF1, OFF3)
Acknowledge: IMMEDIATELY
Cause: A phase failure was detected at the power unit output (motor feeder cable). Chassis power units do not feature phase
failure monitoring.
Note:
The fault can also be signaled if the drive stalled in V/f control. In this particular case, a phase failure does not nec-
essarily have to be present, but a current of 0 was measured in one phase due to current dissymmetry.
Remedy: 1. Check the motor feeder cables.
2. If the drive has stalled in V/f control, the acceleration or deceleration time (p1120) should be increased.
A30016 (N) Power unit: Load supply switched out
Reaction: NONE
Acknowledge: NONE
Cause: The DC link voltage is too low.
Fault value (r0949, interpret decimal):
DC link voltage in [V].
Remedy: Under certain circumstances, the AC line supply is not switched on.
