What it means
F30060 signals that the state monitoring of the precharging contactor has responded. The monitored contactor is the precharging contactor on an ALM, SLM or BLM diode infeed, or the line contactor on a BLM thyristor infeed; the monitoring is active because a feedback signal from the contactor is interconnected. After the contactor is switched in or out, the drive expects the correct feedback signal within the monitoring time set in p0255[0, 2]. If that signal is not received within this time, the drive raises F30060 and switches off; the fault must be acknowledged before the drive can restart. Depending on the drive configuration, the same condition can also be issued as an alarm, in which case no automatic reaction follows and no acknowledgment is required.
Why it appears
- A feedback signal for the precharging contactor (ALM, SLM, BLM diode) or for the line contactor (BLM thyristor) is interconnected and the monitoring is activated.
- After the contactor was switched in or switched out, no correct feedback signal was received within the monitoring time set in p0255[0, 2].
What to check
- Check the monitoring time setting in p0255[0, 2].
- Check the contactor wiring and the contactor activation.
- Replace the contactor.
Reading the message value
- Bit 0: the time set in p0255[0, 2] was exceeded when switching the contactor in or out.
- Bit 1: the precharging contactor was opened while precharging or in the infeed mode (BLM thyristor).
- Bit 2: the precharging contactor was switched in in the OFF state or during infeed operation.
Parameters the manual names
- p0255 (Power unit contactor monitoring time, PU cont t_mon): sets the time within which the contactor feedback signal must arrive after switching — check this setting when F30060 occurs.
- r0949 (fault value): read it in binary form to identify which of the bits (0, 1 or 2) reports the cause of F30060.
Acknowledging and restarting
Acknowledge the fault immediately once the cause has been eliminated; switching POWER ON also removes it. While the fault is active the drive is switched off and cannot restart until it is acknowledged. If the condition is configured as an alarm instead, no acknowledgment is needed.
The same on every family
Every manual that describes F30060 gives it the same reaction, acknowledgement and message class.
| Drive family | Reaction | Acknowledge | Message class | Component | Manual |
|---|---|---|---|---|---|
| S120, S150 | OFF2 (NONE, OFF1) | IMMEDIATELY (POWER ON) | Infeed faulted (13) | Power Module | SINAMICS S120, S150 List Manual · p. 2961 |
| G130, G150 | OFF2 (NONE, OFF1) | IMMEDIATELY (POWER ON) | Infeed faulted (13) | Power Module | SINAMICS G130, G150 List Manual · p. 1669 |

Questions technicians ask
What does fault F30060 on a SINAMICS G130, G150, S120 or S150 mean?
The drive monitors the feedback signal of the precharging contactor (ALM, SLM, BLM diode) or of the line contactor (BLM thyristor). F30060 is raised when the correct feedback signal is not received within the monitoring time set in p0255[0, 2] after the contactor was switched in or out.
How do I clear fault F30060?
Check the monitoring time in p0255[0, 2], then check the contactor wiring and its activation, and replace the contactor if the fault persists. Once the cause is fixed, acknowledge the fault immediately; switching POWER ON also clears it.
What do the bits of the fault value r0949 mean for F30060?
Bit 0 means the monitoring time in p0255[0, 2] was exceeded when switching the contactor in or out. Bit 1 means the precharging contactor was opened while precharging or in the infeed mode (BLM thyristor), and bit 2 means it was switched in in the OFF state or during infeed operation.
Can F30060 also appear as an alarm?
Yes. Depending on the drive configuration, the same condition can be issued as an alarm, which triggers no automatic reaction and requires no acknowledgment.
