207966 <location>Drive: Check the commutation angle
Message -
value:
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 therefore possibly incorrect.
Remedy: Angular commutation offset after the actual value inversion or determine it again (p1990=1).
207967 <location>Drive: Automatic encoder adjustment incorrect
Message %1
value:
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.
207968 <location>Drive: Lq-Ld measurement incorrect
Message %1
value:
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.
207969 <location>Drive: Incorrect pole position identification
Message %1
value:
Drive object: VECTOR
Reaction: OFF2
Acknowledge: IMMEDIATELY
Cause: A fault has occurred during the pole position identification routine.
Fault value (r0949, interpret decimal):
1: Current controller limited
2: Motor shaft locked.
