207989 <location>Drive: Rotating measurement leakage inductance (q-axis)
Message %1
value:
Drive object: VECTOR
Reaction: OFF1 (NONE, OFF2)
Acknowledge: IMMEDIATELY
Cause: An error has occurred while measuring the dynamic leakage inductance.
Fault value (r0949, interpret decimal):
1: The speed did not reach a steady-state condition.
2: The speed setpoint was not able to be approached as the minimum limiting is active.
3: The speed setpoint was not able to be approached as the suppression (skip) bandwidth is active.
4: The speed setpoint was not able to be approached as the maximum limiting is active.
5: The 100% flux setpoint was not reached.
6: No Lq measurement possible because field weakening is active.
7: Speed actual value exceeds the maximum speed p1082 or 75% of the rated motor speed.
8: Speed actual value is below 2 % of the rated motor speed.
Remedy: Re fault value = 1:
- check the motor parameters.
- carry out a motor data identification routine (p1910).
- if required, reduce the dynamic factor (p1967 < 25 %).
Re fault value = 2:
- adapt the speed setpoint (p1965) or adapt the minimum limit (p1080).
Re fault value = 3:
- adapt the speed setpoint (p1965) or suppression (skip) bandwidths (p1091 ... p1094, p1101).
Re fault value = 4:
- adapt the speed setpoint (p1965) or maximum limit (p1082, p1083 and p1086).
Re fault value = 5:
- flux setpoint p1570 = 100% and current setpoint p1610 = 0% kept during the Lq measurement.
Re fault value = 6:
- reduce the regenerative load so that the drive does not reach field weakening when accelerating.
- reduce p1965 so that the q leakage inductance is recorded at lower speeds.
Re fault value = 7:
- increase p1082 if this is technically permissible.
- reduce p1965 so that the q leakage inductance is recorded at lower speeds.
Re fault value = 8:
- reduce the load when motoring so that the drive is not braked.
- increase p1965 so that the measurement is possibly done at higher speeds.
Note:
The measurement of the q leakage inductance can be disabled using p1959.5. If only p1959.5 is set,
then only this measurement is carried out if p1960 is set to 1, 2 and the drive is powered up.

207990 <location>Drive: Incorrect motor data identification
Message %1
value:
Drive object: SERVO, VECTOR
Reaction: OFF2 (NONE, OFF1)
Acknowledge: IMMEDIATELY
Cause: A fault has occurred during the identification routine.
Fault value (r0949, interpret decimal):
1: Current limit value reached.
2: Identified stator resistance lies outside the expected range 0.1 ... 100 % of Zn.
3: Identified rotor resistance lies outside the expected range 0.1 ... 100 % of Zn.
4: Identified stator reactance lies outside the expected range 50 ... 500 % of Zn.
5: Identified magnetizing reactance lies outside the expected range 50 ... 500 % of Zn.
6: Identified rotor time constant lies outside the expected range 10 ms ... 5 s.
7: Identified total leakage reactance lies outside the expected range 4 ... 50 % of Zn.
8: Identified stator leakage reactance lies outside the expected range 2 ... 50 % of Zn.
9: Identified rotor leakage reactance lies outside the expected range 2 ... 50 % of Zn.
