What it means
The manuals print this alarm as PB/PN: clock cycle synchronization missing for DSC
. DSC stands for Dynamic Servo Control. The drive raises A01932 when DSC is selected and, at the same time, there is no clock synchronization or no clock synchronous sign of life in the bus configuration. The G130/G150 and S120/S150 entries carry the same cause and the same remedy; they differ only in the drive objects the alarm can appear on, which the message table lists per family. The remedy is therefore a bus-configuration task, described under checks.
Why it appears
- DSC (Dynamic Servo Control) is selected, but clock synchronization is not set across the bus configuration.
- DSC is selected, but the clock synchronous sign of life is missing.
What to check
- Set clock synchronization across the bus configuration.
- Transfer the clock synchronous sign-of-life.
- Check the result with r2064 (PB/PN diagnostics clock cycle synchronism), the parameter the remedy points to.
Parameters the manual names
- p0922 — IF1 PROFIdrive PZD telegram selection; cross-referenced by both entries for this alarm.
- r2064 — PB/PN diagnostics clock cycle synchronism; the parameter the remedy names for checking the clock cycle synchronism of the bus configuration.
- p1190 — CI: DSC position deviation XERR; a DSC parameter cross-referenced with this alarm in the S120/S150 entry.
- p1191 — CI: DSC position controller gain KPC; a DSC parameter cross-referenced with this alarm in the S120/S150 entry.
Acknowledging and restarting
No acknowledgement is required for this alarm, and the drive takes no automatic reaction to it. The condition behind A01932 is removed by setting clock synchronization across the bus configuration and transferring the clock synchronous sign of life, as described under checks.
The same on every family
Every manual that describes A01932 gives it the same reaction, acknowledgement and message class.
| Drive family | Reaction | Acknowledge | Message class | Component | Manual |
|---|---|---|---|---|---|
| S120, S150 | NONE | NONE | Error in the parameterization / configuration / commissioning procedure (18) | None | SINAMICS S120, S150 List Manual · p. 2717 |
| G130, G150 | NONE | NONE | Error in the parameterization / configuration / commissioning procedure (18) | None | SINAMICS G130, G150 List Manual · p. 1493 |

Questions technicians ask
What does alarm A01932 mean on a SINAMICS drive?
It means DSC (Dynamic Servo Control) is selected while clock synchronization or the clock synchronous sign of life is missing across the bus configuration. The manuals describe it for G130, G150, S120 and S150.
How do I clear alarm A01932?
Set clock synchronization across the bus configuration and transfer the clock synchronous sign of life. You can watch the clock cycle synchronism with r2064 (PB/PN diagnostics clock cycle synchronism).
Does A01932 have to be acknowledged?
No. The alarm requires no acknowledgement and the drive takes no automatic reaction; the correction is made in the bus configuration.
Which parameters are associated with A01932?
The manuals cross-reference p0922 (IF1 PROFIdrive PZD telegram selection) and r2064 (PB/PN diagnostics clock cycle synchronism). The S120/S150 entry additionally names the DSC parameters p1190 (DSC XERR) and p1191 (DSC KPC).
