What it means
F01687 is a fault of the Safety Integrated (SI) Motion functions: the modulo value parameterized for the "Safe Cam" (SCA) function is not a multiple of 360 000 mDegrees. The abbreviations in the code title stand for SCA = Safe Cam, SN = Safe software cam and SI = Safety Integrated. On this fault the drive coasts down (OFF2). The manual notes explicitly that this fault does not result in a safety stop response, so no safety-oriented stop is triggered.
Why it appears
- The modulo value parameterized for the "Safe Cam" (SCA) function is not a multiple of 360 000 mDegrees.
What to check
- Check the modulo value set for the SCA function — for this fault the drive references p9505 (SI Motion SP modulo value, Control Unit).
- Correct the modulo value so that it is a multiple of 360 000 mDegrees.
- Carry out a POWER ON to acknowledge the fault.
Parameters the manual names
- p9505 — SI Motion SP modulo value (Control Unit): the modulo-value parameter referenced for this fault; correct the value here so that it is a multiple of 360 000 mDegrees, then carry out a POWER ON.
Acknowledging and restarting
Correct the modulo value for SCA and then carry out a POWER ON
. The fault is acknowledged with this POWER ON — the drive becomes ready to restart only once the power has been switched off and back on after the correction. As the manual notes, the fault does not result in a safety stop response.
The same on every family
Every manual that describes F01687 gives it the same reaction, acknowledgement and message class.

| G130, G150 | OFF2 | IMMEDIATELY (POWER ON) | Error in the parameterization / configuration / commissioning procedure (18) | None | SINAMICS G130, G150 List Manual · p. 1456 |
