SINAMICS alarms
Status, power unit (upper 16 bit, hexadecimal number):
0: Fault status (wait for OFF and fault acknowledgement)
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 STO terminal was energized at the power unit

Remedy:
In general:
- check the line supply voltage at the input terminals.
- check the line supply voltage setting (p0210).
- the following applies to booksize units: Wait (approx. 8 min.) until the pre-charging resistors have cooled down. For
this purpose, preferably disconnect the infeed unit from the line supply.
Re 5):
- carefully observe the permissible pre-charging frequency (refer to the appropriate Equipment Manual).
Re 6):
- check the total capacitance of the DC link and reduce in accordance with the maximum permissible DC-link capaci-
tance if necessary (refer to the appropriate Equipment Manual)
Re 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
Re 8):
- check the connections of the external line contactor. The line contactor must be open during DC-link fast discharge.
Re 9):
- check the DC link for ground faults or short circuits.

230031
<location>Power unit: Hardware current limiting, phase U
Message value:
-
Drive object:
AFE_SINUMERIK_828, BIC_SINUMERIK_828, SERVO_COMBI, SERVO_SINUMERIK828, SIC_COMBI,
SIC_SINUMERIK_828
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.
- motor load too high
- power unit defective.
Note:
Alarm A30031 is always output if, for a Power Module, the hardware current limiting of phase U, V or W responds.
Remedy:
- check the motor data.
- check the motor circuit configuration (star-delta)
- check the motor load.
- check the power cable connections.
- check the power cables for short-circuit or ground fault.
- check the length of the power cables.
