SINAMICS G120 Control Units CU230P-2 Parameter Manual (LH9), 01/2011
F30012 Power unit: Temperature sensor heat sink wire breakage
Reaction: OFF1 (OFF2)
Acknowledge: IMMEDIATELY
Cause: The connection to a heat sink temperature sensor 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 (N, A) Power unit: Phase failure motor cable
Reaction: OFF2 (NONE, OFF1, OFF3)
Acknowledge: IMMEDIATELY
Cause: A phase failure in the motor feeder cable was detected.
The signal can also be output in the following cases:
- The motor is correctly connected, but the drive has stalled in V/f control. In this case, a current of 0 A is possibly
measured in one phase due to asymmetry of the currents.
- the motor is correctly connected, however the closed-speed control is instable and therefore an oscillating torque
is generated.
Note:
Chassis power units do not feature phase failure monitoring.
Remedy: - check the motor feeder cables.
- increase the ramp-up or ramp-down time (p1120) if the drive has stalled in V/f control.
- check the speed controller settings.
A30016 (N) Power unit: Load supply switched out
Reaction: NONE
Acknowledge: NONE
Cause: The DC link voltage is too low.
Alarm value (r2124, interpret decimal):
DC link voltage at the time of trip [0.1 V].
Remedy: Under certain circumstances, the AC line supply is not switched on.
