F07413 — Drive: Commutation angle incorrect (pole position identification)

F07413 is raised when the drive detects an incorrect commutation angle: the angle established for the motor deviates from the angle of the motor encoder, and the manual notes that such a mismatch can result in positive coupling in the speed controller. The plausibility check behind the fault runs in two situations — within the pole position identification routine (p1982 = 2) and, for VECTOR, within the encoder adjustment (p1990 = 2) — and each situation has its own deviation limit.

• Within the pole position identification routine (p1982 = 2), a difference of more than 45 ° electrical to the encoder angle was determined.
• For VECTOR, within the encoder adjustment (p1990 = 2), a difference of more than 6 ° electrical to the encoder angle was determined.

1. Correctly set the angular commutation offset (p0431).
2. Re-adjust the motor encoder after the encoder has been replaced — the encoder adjustment runs with p1990 = 2.
3. Replace the defective motor encoder.
4. Check the pole position identification routine. If the routine is not suitable for this motor type, disable the plausibility check by setting p1982 = 0.

• p0431 (angular commutation offset) — the offset to set correctly so that the commutation angle matches the motor encoder.
• p1982 (PolID selection) — set to 2 to run pole position identification; set to 0 to disable the plausibility check when the routine does not suit the motor type.
• p1990 (encoder adjustment, determine angular commutation offset) — the adjustment run with p1990 = 2, used to re-adjust the motor encoder after it has been replaced.

Remove the cause first — correct p0431, re-adjust the motor encoder, or replace it if defective — and then acknowledge the fault immediately. If pole position identification is repeated as part of the correction, it is started with p1982 = 2; where the routine is unsuitable for the motor, the plausibility check remains disabled with p1982 = 0.
