F07970 Drive: Automatic encoder adjustment incorrect
Message value: %1
Message class: Error in the parameterization / configuration / commissioning procedure (18)
Drive object: VECTOR_G
Reaction: OFF2 (NONE)
Acknowledge: IMMEDIATELY
Cause: A fault has occurred during the automatic encoder adjustment.
Fault value (r0949, interpret decimal):
1: Current controller limited
2: Motor shaft locked.
4: Encoder speed signal not plausible.
5: Deselect U/f (p1300) or deactivate encoder calibration (p1990).
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.
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:
Open the motor holding brake (p1215 = 2) and bring the motor into a no-load condition.
For fault value = 4:
Check whether the speed actual value inversion is correct (p0410.0).
Check whether the motor is correctly connected.
Check whether the encoder pulse number (p0408) and gearbox factor (p0432, p0433) are correct.
Check whether the motor pole pair number is correct (p0314).
For fault value = 5:
Deselect U/f (p1300) or deactivate encoder calibration (p1990).
For fault value = 10:
Increase the value for p0325.
Check whether the motor is correctly connected.
Replace the power unit involved.
For fault value = 11:
Increase the value for p0329.
Check whether the motor is correctly connected.
Replace the power unit involved.
For fault value = 12:
Reduce the value for p0325.
Check whether motor data have been correctly entered.
For fault value = 13:
Reduce the value for p0329.
Check whether motor data have been correctly entered.
For fault value = 14:
Increase the value for p0329.
For fault value = 15:
Increase the value for p0325.
For fault value = 16:
De-activate technique (p1982).
