Cause: A fault has occurred during the automatic encoder adjustment.
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.
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: Re fault value = 1:
Check whether the motor is correctly connected.
Check whether motor data have been correctly entered.
Replace the Motor Module involved.
Re fault value = 2:
Open the motor holding brake (p1215) and bring the motor into a no-load condition.
Re 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).
Re fault value = 10:
Increase the value for p0325.
Check whether the motor is correctly connected.
Replace the Motor Module involved.
Re fault value = 11:
Increase the value for p0329.
Check whether the motor is correctly connected.
Replace the Motor Module involved.
Re fault value = 12:
Reduce the value for p0325.
Check whether motor data have been correctly entered.
Re fault value = 13:
Reduce the value for p0329.
Check whether motor data have been correctly entered.
Re fault value = 14:
Increase the value for p0329.
Re fault value = 15:
Increase the value for p0325.
Re fault value = 16:
De-activate traversing/moving (p1982).
Re fault value = 17:
Repeat traversing.
207971 <location>Drive: Angular commutation offset determination activated
Message -
value:
Drive object: SERVO, VECTOR
Reaction: NONE
Acknowledge: NONE
Cause: The automatic determination of the angular commutation offset (encoder adjustment) is activated
(p1990 = 1).
The automatic determination is carried out with the next power-on command.
For SERVO and fault F07414 present, the following applies:
The determination of the angular commutation offset is automatically activated (p1990 = 1), if a pole
position identification technique is set in p1980.
See also: p1990 (Encoder adjustment, determine angular commutation offset)
Remedy: None necessary.
The alarm automatically disappears after determination or for the setting p1990 = 0.
