Re fault value 3820 - 3829:
- check the load at speed p382x.
- check the speed signal (r0063) for oscillation at speed p382x. If required, check the speed controller settings.
Re fault value = 3840:
Make the friction characteristic error-free (p3820 - p3829, p3830 - p3839, p3840).
Re fault value = 3845:
Activate the friction characteristic record (p3845).
F07966 Drive: Check the commutation angle
Drive object: SERVO
Reaction: OFF2 (NONE)
Acknowledge: IMMEDIATELY
Cause: The speed actual value was inverted and the associated angular commutation offset is not equal to zero and is there-
fore possibly incorrect.
Remedy: Angular commutation offset after the actual value inversion or determine it again (p1990=1).
F07967 Drive: Automatic encoder adjustment incorrect
Drive object: VECTOR
Reaction: OFF2 (NONE, OFF1)
Acknowledge: IMMEDIATELY
Cause: A fault has occurred during the automatic encoder adjustment or the pole position identification.
Only for internal Siemens troubleshooting.
Remedy: Carry out a POWER ON.
F07968 Drive: Lq-Ld measurement incorrect
Drive object: VECTOR
Reaction: OFF2
Acknowledge: IMMEDIATELY
Cause: A fault has occurred during the Lq-Ld measurement.
Fault value (r0949, interpret decimal):
10: Stage 1: The ratio between the measured current and zero current is too low.
12: Stage 1: The maximum current was exceeded.
15: Second harmonic too low.
16: Drive converter too small for the measuring technique.
17: Abort due to pulse inhibit.
Remedy: Re fault value = 10:
Check whether the motor is correctly connected.
Replace the Motor Module involved.
De-activate traversing (p1909).
Re fault value = 12:
Check whether motor data have been correctly entered.
De-activate traversing (p1909).
Re fault value = 16:
De-activate traversing (p1909).
Re fault value = 17:
Repeat traversing.
F07969 Drive: Incorrect pole position identification
Drive object: VECTOR
Reaction: OFF2
Acknowledge: IMMEDIATELY
Cause: A fault has occurred during the pole position identification routine.
Fault value (r0949, decimal):
1: Current controller limited
2: Motor shaft locked.
4: Encoder speed signal not plausible.
10: Stage 1: The ratio between the measured current and zero current is too low.
11: Stage 2: The ratio between the measured current and zero current is too low.
12: Stage 1: The maximum current was exceeded.
