4.2 List of faults and alarms

1630 List Manual (LH2), 07/2016, A5E03263479A
For fault value = 2:
- adapt the speed setpoint (p1965) or adapt the minimum limit (p1080).
For fault value = 3:
- adapt the speed setpoint (p1965) or suppression (skip) bandwidths (p1091 ... p1094, p1101).
For fault value = 4:
- adapt the speed setpoint (p1965) or maximum limit (p1082, p1083 and p1086).
For fault value = 5:
- flux setpoint p1570 = 100 % and current setpoint p1610 = 0 % kept during the Lq measurement.
For 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.
For fault value = 7:
- increase p1082, if this is technically permissible.
- reduce p1965 so that the q leakage inductance is recorded at lower speeds.
For fault value = 8:
- reduce the load when motoring so that the drive is not braked.
- increase p1965 so that the measurement may be taken 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 switched on.
