What it means
A30065 reports that the voltage measurement is not supplying any plausible values. Depending on how the drive is configured, the same condition can also be issued as a fault (F) or as a message without an automatic reaction (N). The alarm value stored in r2124 tells you which phase the drive objects to.
Why it appears
- The voltage measurement is not delivering plausible values.
What to check
- Deactivate the voltage measurement: set p0247.0 = 0.
- Deactivate flying restart with voltage measurement: set p0247.5 = 0.
- Deactivate the fast flying restart: set p1780.11 = 0.
- No other remedial action is described for this message.
Reading the message value
- The drive stores the alarm value in r2124; interpret it bitwise binary.
- Bit 1: Phase U.
- Bit 2: Phase V.
- Bit 3: Phase W.
Parameters the manual names
- r2124 — alarm value: read the bits to see which phase (U, V or W) the drive finds implausible.
- p0247 — voltage measurement configuration: set bit 0 = 0 to switch the voltage measurement off and bit 5 = 0 to switch flying restart with voltage measurement off.
- p1780 — motor model adaptation configuration: set bit 11 = 0 to switch the fast flying restart off.
Acknowledging and restarting
As an alarm, A30065 needs no acknowledgment. If the drive's configuration raises the same condition as a fault, the response is still none — the drive does not execute OFF1, OFF2, OFF3 or STOP2 — and the fault must then be acknowledged immediately.
What differs between the drive families
Straight from the manuals' own fields — A30065 is not described identically everywhere.
| Drive family | Reaction | Acknowledge | Message class | Component | Manual |
|---|---|---|---|---|---|
| S120, S150 | NONE | NONE | Power electronics faulted (5) | Power Module | SINAMICS S120, S150 List Manual · p. 2962 |
| G130, G150 | NONE | NONE | Power electronics faulted (5) | Power Module | SINAMICS G130, G150 List Manual · p. 1670 |
| G120 | NONE | NONE | Power electronics faulted (5) | — | SINAMICS G120 · p. 916 |

Questions technicians ask
What does SINAMICS alarm A30065 mean?
It means the voltage measurement is not supplying any plausible values. The alarm value in r2124 shows bitwise which phase — U, V or W — is affected.
How do I acknowledge or reset A30065?
As an alarm it needs no acknowledgment. If the same condition is raised as a fault, the drive performs no automatic stop and the fault is acknowledged immediately.
Which parameters switch off the voltage measurement for A30065?
Set p0247.0 = 0 to deactivate the voltage measurement. To also switch off the related restart functions, set p0247.5 = 0 and p1780.11 = 0.
Can A30065 also appear as a fault?
Yes — depending on the drive's configuration, the same condition can also be issued as a fault (F) or without an automatic reaction (N).
