4 Faults and alarms
4.2 List of faults and alarms
F07967 Drive: Incorrect pole position identification
Message class: Error in the parameterization / configuration / commissioning procedure (18)
Reaction: OFF2 (NONE, OFF1)
Acknowledge: IMMEDIATELY
Cause: A fault has occurred during the pole position identification routine.
Only for internal Siemens troubleshooting.
Remedy: Carry out a POWER ON.
F07968 Drive: Lq-Ld measurement incorrect
Message class: Error in the parameterization / configuration / commissioning procedure (18)
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.
De-activate technique (p1909).
For fault value = 12:
Check whether motor data have been correctly entered.
De-activate technique (p1909).
For fault value = 16:
De-activate technique (p1909).
For fault value = 17:
Repeat technique.
F07969 Drive: Incorrect pole position identification
Message class: Error in the parameterization / configuration / commissioning procedure (18)
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.
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.
13: Stage 2: The maximum current was exceeded.
14: Current difference to determine the +d axis too low.
15: Second harmonic too low.
16: Drive converter too small for the measuring technique.
17: Abort due to pulse inhibit.
18: First harmonic too low.
20: Pole position identification requested with the motor shaft rotating and activated "flying restart" function.
Remedy: For fault value = 1:
Check whether the motor is correctly connected.
Check whether motor data have been correctly entered.
Replace the power unit involved.
For fault value = 2:
Bring the motor into a no-load condition.
