Power Unit: Load Supply Switched Out; Power Unit: Hardware Current Limit Has Responded Too Often - Siemens SINAMICS S210 Operating Instructions Manual

Faults and alarms
13.2 List of faults and alarms
Acknowl. upon N: NONE
Reaction upon A: NONE
Acknowl. upon A: NONE
A30016 (N)

Power unit: Load supply switched out

Message value: %1
Drive object: All objects
Reaction: NONE
Acknowledge: NONE
Cause: The DC link voltage is too low.
Alarm value (r2124, interpret decimal):
DC link voltage at the time of trip [0.1 V].
Remedy: - switch on load supply.
- check the line supply if necessary.
Reaction upon N: NONE
Acknowl. upon N: NONE
F30017

Power unit: Hardware current limit has responded too often

Message value: Fault cause: %1 bin
Drive object: All objects
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.
For infeed units, the following applies:
- closed-loop control is incorrectly parameterized.
- load on the infeed is too high.
- Voltage Sensing Module incorrectly connected.
- line reactor missing or the incorrect type.
- power unit defective.
The following applies to Motor Modules:
- 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.
Fault value (r0949, interpret binary):
Bit 3: phase U
Bit 4: phase V
Bit 5: phase W
Additional bits:
Only for internal Siemens troubleshooting.
Note:
Fault value = 0 means that the phase with current limiting is not recognized (e.g. for blocksize device).
