What it means
A30010 Power unit: Sign-of-life error cyclic data reports a DRIVE-CLiQ communication error between the Control Unit (CU) and the power unit involved. The power unit did not receive the Control Unit's cyclic setpoint telegrams on time — they were missing for at least one clock cycle.
Depending on the drive's configuration, the same condition can also be output as a fault instead of this alarm.
Why it appears
- A communication error has occurred on the DRIVE-CLiQ link between the Control Unit and the power unit involved.
- The power unit failed to receive the Control Unit's cyclic setpoint telegrams on time for at least one clock cycle.
What to check
- Check the Motor Module.
- If the check shows this is required, replace the Motor Module.
Acknowledging and restarting
No acknowledgment is specified for the alarm form, and the drive takes no automatic reaction while the alarm is present. If the drive's configuration raises the same condition as a fault instead, the manual likewise lists no automatic reaction for the infeed, servo and vector drive objects involved, and specifies the acknowledgment for the fault variant as IMMEDIATELY (POWER ON)
.
The same on every family
Every manual that describes A30010 gives it the same reaction, acknowledgement and message class.
| Drive family | Reaction | Acknowledge | Message class | Component | Manual |
|---|---|---|---|---|---|
| S120, S150 | NONE | NONE | Internal (DRIVE-CLiQ) communication error (12) | Control Unit (CU) | SINAMICS S120, S150 List Manual · p. 2940 |
| G130, G150 | NONE | NONE | Internal (DRIVE-CLiQ) communication error (12) | Control Unit (CU) | SINAMICS G130, G150 List Manual · p. 1652 |

Questions technicians ask
What does SINAMICS alarm A30010 mean?
It reports a DRIVE-CLiQ communication error between the Control Unit and the power unit involved: the power unit did not receive the Control Unit's cyclic setpoint telegrams on time for at least one clock cycle.
How do I clear SINAMICS A30010?
Check the Motor Module and replace it if required. The alarm needs no acknowledgment; if the condition appears as a fault instead, the manual specifies acknowledgment IMMEDIATELY (POWER ON).
Does A30010 trip the drive?
No automatic reaction is specified for the alarm. Even as a fault, the manual lists no automatic reaction for the infeed, servo and vector drive objects involved.
Can A30010 also appear as a fault?
Yes — the drive's configuration decides whether the same sign-of-life condition in the cyclic data is issued as alarm A30010 or as a fault.
