Power Unit: Temperature Sensor Heat Sink Wire Breakage; Power Unit: Temperature Sensor Heat Sink Short-Circuit; Power Unit: Hardware Current Limit Has Responded Too Often - Siemens SINAMICS DCM List Manual

4 Faults and alarms
4.2 List of faults and alarms
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

Remedy: Contact the manufacturer.
F30013

Power unit: Temperature sensor heat sink short-circuit

Message value: %1
Message class: Power electronics faulted (5)
Drive object: DC_CTRL, DC_CTRL_R, DC_CTRL_R_S, DC_CTRL_S
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.
F30017

Power unit: Hardware current limit has responded too often

Message value: Fault cause: %1 bin
Message class: Power electronics faulted (5)
Drive object: DC_CTRL, DC_CTRL_R, DC_CTRL_R_S, DC_CTRL_S
Reaction: OFF2
Acknowledge: IMMEDIATELY
Cause: The hardware current limitation in the relevant phase (see A30031, A30032, A30033) has responded too often. The
number of times the limit has been exceeded depends on the design and type of power unit.
