What it means
The drive reports that the position tracking of the measuring gear on Encoder 2 cannot be reset. The S120/S150 and G130/G150 manuals describe this condition identically. Depending on how the drive is configured, the same condition can also be signalled as an alarm or without any drive reaction instead of as a fault.
Why it appears
- The position tracking of the measuring gear cannot be reset by the drive.
What to check
- Select encoder commissioning: set p0010 = 4.
- Reset the position tracking: set p0411.2 = 1.
- Deselect encoder commissioning: set p0010 = 0.
- Acknowledge the fault and then adjust the absolute encoder.
Parameters the manual names
- p0010 — the drive commissioning parameter filter; set it to 4 to select encoder commissioning before the reset and back to 0 afterwards.
- p0411 — the measuring gear configuration; setting bit 2 to 1 performs the reset of the position tracking.
Acknowledging and restarting
Once encoder commissioning has been deselected again (p0010 = 0), acknowledge the fault; the remedy concludes by adjusting the absolute encoder.
What differs between the drive families
Straight from the manuals' own fields — F32503 is not described identically everywhere.
| Drive family | Reaction | Acknowledge | Message class | Component | Manual |
|---|---|---|---|---|---|
| S120, S150 | OFF1 (NONE, OFF2, OFF3) | — | Actual position/speed value incorrect or not available (11) | None | SINAMICS S120, S150 List Manual · p. 3113 |
| G130, G150 | OFF1 (NONE, OFF2, OFF3) | IMMEDIATELY | Actual position/speed value incorrect or not available (11) | None | SINAMICS G130, G150 List Manual · p. 1791 |
The drives this code lives on

Questions technicians ask
What does fault F32503 on a SINAMICS drive mean?
It means the drive cannot reset the position tracking of the measuring gear on Encoder 2. The manuals describe it identically for the S120, S150, G130 and G150 families.
How do I clear F32503?
Select encoder commissioning with p0010 = 4, set p0411.2 = 1 to reset the position tracking, then set p0010 = 0. Afterwards acknowledge the fault and adjust the absolute encoder.
Can F32503 also appear as an alarm?
Yes. Depending on the drive's configuration, the same condition can be signalled as an alarm or without any drive reaction instead of as a fault.
Which parameters are involved in F32503?
p0010, the drive commissioning parameter filter, selects and deselects encoder commissioning, and p0411, the measuring gear configuration, performs the reset via bit 2.
