What it means
F07446 is raised when the drive cannot reset the position tracking of the load gear. The S120/S150 and the G130/G150 manuals describe the code with the same cause and the same remedy, so one procedure covers both families. Depending on the drive configuration, the same condition can also be output as an alarm (A); as an alarm it causes no reaction and does not need to be acknowledged.
Why it appears
- The position tracking of the load gear cannot be reset.
What to check
- Select encoder commissioning: set p0010 = 4.
- Reset the position tracking position: set p2720.2 = 1.
- Deselect encoder commissioning: set p0010 = 0.
Parameters the manual names
- p0010 — drive commissioning parameter filter: set to 4 to select encoder commissioning for the reset, then back to 0 to deselect it afterwards.
- p2720 — load gear configuration: bit 2 (p2720.2 = 1) performs the reset of the position tracking position.
- p2507 — LR absolute encoder adjustment status: named in the remedy when the absolute encoder has to be re-adjusted, if this proves necessary.
Acknowledging and restarting
Acknowledge the fault once encoder commissioning has been deselected; the drive can then be started again. If it proves necessary, re-adjust the absolute encoder (p2507) as the final step of the remedy.
The same on every family
Every manual that describes F07446 gives it the same reaction, acknowledgement and message class.
| Drive family | Reaction | Acknowledge | Message class | Component | Manual |
|---|---|---|---|---|---|
| S120, S150 | OFF1 (OFF2, OFF3) | IMMEDIATELY | Application/technological function faulted (17) | None | SINAMICS S120, S150 List Manual · p. 2817 |
| G130, G150 | OFF1 (OFF2, OFF3) | IMMEDIATELY | Application/technological function faulted (17) | None | SINAMICS G130, G150 List Manual · p. 1554 |

Questions technicians ask
What does SINAMICS fault F07446 mean?
The drive is signaling that the position tracking of the load gear cannot be reset. Depending on the configuration, the same condition can also be output as an alarm (A) instead of a fault.
How do I clear fault F07446?
Select encoder commissioning (p0010 = 4), reset the position tracking position (p2720.2 = 1), then deselect encoder commissioning (p0010 = 0). Acknowledge the fault afterwards and, if necessary, re-adjust the absolute encoder (p2507).
Which parameters are used with F07446?
p0010 selects and deselects encoder commissioning, p2720.2 = 1 performs the reset of the position, and p2507 comes into play if the absolute encoder has to be re-adjusted.
Does F07446 have to be acknowledged when it appears as an alarm?
No. When the condition is output as an alarm (A), the drive does not react and the message does not need to be acknowledged.
