4.2 List of faults and alarms
F30011 Power unit: Line phase failure in main circuit
Message class: Network fault (2)
Reaction: OFF2 (OFF1)
Acknowledge: IMMEDIATELY
Cause: At the power unit, the DC link voltage ripple has exceeded the permissible limit value.
Possible causes:
- A line phase has failed.
- The 3 line phases are inadmissibly unsymmetrical.
- The capacitance of the DC link capacitor forms a resonance frequency with the line inductance and the reactor
integrated in the power unit.
- the fuse of a phase of a main circuit has ruptured.
- A motor phase has failed.
Fault value (r0949, interpret decimal):
Only for internal Siemens troubleshooting.
Remedy: - check the main circuit fuses.
- Check whether a single-phase load is distorting the line voltages.
- Detune the resonant frequency with the line inductance by using an upstream line reactor.
- Dampen the resonant frequency with the line inductance by switching over the DC link voltage compensation in the
software (see p1810) – or increase the smoothing (see p1806). However, this can have a negative impact on the
torque ripple at the motor output.
- check the motor feeder cables.
F30012 Power unit: Temperature sensor heat sink wire breakage
Message class: Power electronics faulted (5)
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
Message class: Power electronics faulted (5)
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
