Bit 13: Vce fault detected, transistor de-saturated due to overcurrent/short-circuit.
Bit 14: Undervoltage detected.
See also: p0210 (Drive unit line supply voltage)
Remedy: In general:
- check the line supply voltage at the input terminals.
- check the line supply voltage setting (p0210).
For booksize drive units, the following applies:
- wait (approx. 8 minutes) until the precharging resistors have cooled down. For this purpose, preferably disconnect
the infeed unit from the line supply.
For 5):
- carefully observe the permissible precharging frequency (refer to the appropriate Equipment Manual).
For 6):
- check the total capacitance of the DC link and reduce in accordance with the maximum permissible DC link
capacitance if necessary (refer to the appropriate Equipment Manual)
For 7):
- interconnect the ready-for-operation signal from the infeed unit (r0863.0) in the enable logic of the drives connected
to this DC link
For 8):
- check the connections of the external line contactor. The line contactor must be open during DC link fast discharge.
For 9):
- check the DC link for ground faults or short circuits.
For 11):
- check the DC link voltage of the infeed (r0070) and Motor Modules (r0070).
If the DC link voltage generated by the infeed (or external) is not displayed for the Motor Modules (r0070), then a fuse
has ruptured in the Motor Module.

A30030 Power unit: Internal overtemperature alarm
Message value: %1
Message class: Power electronics faulted (5)
Drive object: B_INF, VECTOR_G
Component: Power Module
Reaction: NONE
Acknowledge: NONE
Cause: The temperature inside the drive converter has exceeded the permissible temperature limit.
- insufficient cooling, fan failure.
- overload.
- ambient temperature too high.
Alarm value (r2124, interpret decimal):
Only for internal Siemens troubleshooting.
Remedy: - possibly use an additional fan.
- check whether the ambient temperature is in the permissible range.
Notice:
This fault can only be acknowledged once the permissible temperature limit minus 5 K has been fallen below.
A30031 Power unit: Hardware current limiting in phase U
Message value: -
Message class: Power electronics faulted (5)
Drive object: B_INF, VECTOR_G
Component: Power Module
Reaction: NONE
Acknowledge: NONE
Cause: Hardware current limit for phase U responded. The pulsing in this phase is inhibited for one pulse period.
- closed-loop control is incorrectly parameterized.
- fault in the motor or in the power cables.
- the power cables exceed the maximum permissible length.
