Remedy: The faults are saved in the TCB and are acknowledged by switching-out the TCB supply
voltage for at least 10 s!
- check the line supply voltage
- check or energize the line contactor.
- check the monitoring time and, if required, increase (p0857).
- if required, observe additional power module messages/signals.
- check the DC link regarding short-circuit or ground fault.
- observe the LED fault display of the thyristor control board.
230010 <location>Power module: Sign-of-life, cyclic data
Reaction: NONE
Acknowledge: NONE
Cause: A DRIVE-CLiQ communications error has occurred between the control unit and the power
module involved.
The cyclic setpoint telegrams of the control unit were not received on time by the power
module for at least one clock cycle.
Remedy: - check the electrical cabinet design and cable routing for EMC compliance
230011 <location>Power module: Line phase failure in main circuit
Reaction: OFF2 (OFF1)
Acknowledge: IMMEDIATELY
Cause: A line phase failure was detected at the power module.
- the fuse of a phase of a main circuit has ruptured.
- the DC link voltage ripple has exceeded the permissible limit value.
Remedy: Check the fuses in the main circuit.
230012 <location>Power module: Temperature sensor heatsink wire breakage
Reaction: OFF1 (OFF2)
Acknowledge: IMMEDIATELY
Cause: The connection to one of the heatsink temperature sensors in the power module is
interrupted.
Fault value (r0949, 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
See also: r0949
Remedy: Contact the manufacturer.
230013 <location>Power module: Temperature sensor heatsink short-circuit
Reaction: OFF1 (OFF2)
Acknowledge: IMMEDIATELY
