Remedy:
- adapt the load duty cycle.
- check whether the fan is running.
- check the fan elements
- check whether the ambient temperature is in the permissible range.
- check the motor load.
- reduce the pulse frequency if this is higher than the rated pulse frequency.
Notice:
This fault can only be acknowledged after this alarm threshold for alarm A05001 has been fallen below.

F30027
Power module: Precharging DC link monitoring
Reaction:
OFF2
Acknowledge:
IMMEDIATELY
Cause:
The power module DC link was not able to be pre-charged within the expected time.
- line supply voltage too low.
- line supply phase fault.
- short-circuit or ground fault in the DC link.
- pre-charging circuit defective.
Fault value (r0949):
Missing internal enable signals, power module (lower 16 bit):
(Inverted bit-coded notation FFFF hex -> all internal enable signals available)
Bit 0: Power supply of the IGBT gating shut down
Bit 1: Reserved
Bit 2: Reserved
Bit 3: Ground fault detected
Bit 4: Peak current intervention
Bit 5: I2t exceeded
Bit 6: Thermal model, overtemperature calculated
Bit 7: (heatsink, gating module, power module) overtemperature measured
Bit 8: Reserved
Bit 9: Overvoltage detected
Bit 10: Power module has completed pre-charging, ready for pulse enable
Bit 11: SH terminal missing
Bit 12: Overcurrent condition detected
Bit 13: Armature short-circuit
Bit 14: DRIVE-CLiQ fault active
Bit 15: Vce fault detected, transistor de-saturated due to overcurrent/circuit-circuit
Status, power module (upper 16 bit, hexadecimal number):
0: Fault status (wait for OFF and fault acknowledgment)
1: Restart inhibit (wait for OFF)
2: Overvoltage condition detected -> change into the fault state
3: Undervoltage condition detected -> change into the fault state
4: Wait for bypass contactor to open -> change into the fault state
5: Wait for bypass contactor to open -> change into restart inhibit
6: Commissioning
7: Ready for pre-charging
8: Pre-charging started, DC link voltage lower than the minimum switch-on voltage
9: Pre-charging, DC link voltage end of pre-charging still not detected
10: Wait for the end of the de-bounce time of the main contactor after pre-charging has been completed
11: Pre-charging completed, ready for pulse enable
12: It was detected that the SH terminal was energized at the power module
