4.2 List of faults and alarms
For fault value = 3840:
- Make the friction characteristic error-free (p3820 ... p3829, p3830 ... p3839, p3840).
For fault value = 3845:
- Activate the friction characteristic record (p3845).
F07967 Drive: Automatic encoder adjustment/pole position identification incorrect
Message value: %1
Message class: Error in the parameterization / configuration / commissioning procedure (18)
Drive object: VECTOR_G
Component: None Propagation: GLOBAL
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
Message value: %1
Message class: Error in the parameterization / configuration / commissioning procedure (18)
Drive object: VECTOR_G
Component: None Propagation: GLOBAL
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: For fault value = 10:
Check whether the motor is correctly connected.
Replace the power unit involved.
Deactivate technique (p1909).
For fault value = 12:
Check whether motor data have been correctly entered.
Deactivate technique (p1909).
For fault value = 16:
Deactivate technique (p1909).
For fault value = 17:
Repeat technique.
F07969 Drive: Incorrect pole position identification
Message value: %1
Message class: Error in the parameterization / configuration / commissioning procedure (18)
Drive object: VECTOR_G
Component: None Propagation: GLOBAL
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.
4: Encoder speed signal not plausible.
10: Stage 1: The ratio between the measured current and zero current is too low.
