A07983
Drive: Speed controller optimization, saturation characteristic
Reaction:
NONE
Acknowledge:
NONE
Cause:
A fault has occurred while determining the saturation characteristic.
Alarm value (r2124, decimal):
1: The speed did not reach a steady-state condition.
2: The rotor flux did not reach a steady-state condition.
3: The adaptation circuit did not reach a steady-state condition.
4: The adaptation circuit was not enabled.
5: Field weakening active.
6: The speed setpoint was not able to be approached as the minimum limiting is active.
7: The speed setpoint was not able to be approached as the suppression (skip) bandwidth is active.
8: The speed setpoint was not able to be approached as the maximum limiting is active.
9: Several values of the determined saturation characteristic are not plausible.
10: Saturation characteristic could not be sensibly determined because load torque too large.
Remedy:
Re alarm value = 1 ... 4:
- check the motor parameters.
- carry-out a motor data identification routine (p1910).
- if required, reduce the dynamic factor (p1967 < 0.25).
Re alarm value = 5:
The speed setpoint (p1961) is too high. Reduce the speed.
Re alarm value = 6:
Adapt the speed setpoint (p1961) or minimum limiting (p1080).
Re alarm value = 7:
Adapt the speed setpoint (p1961) or suppression (skip) bandwidths (p1091 ... p1094, p1101).
Re alarm value = 8:
Adapt the speed setpoint (p1961) or maximum limiting (p1082, p1083 and p1086).
Re alarm value = 9, 10:
The measurement was carried-out at an operating point where the load torque is too high. Select a more suitable
operating point, either by changing the speed setpoint (p1961) or by reducing the load torque. The load torque may
not be varied while making measurements.
Note:
The saturation characteristic identification routine can be disabled using p1959.1.

A07984
Drive: Speed controller optimization, moment of inertia
Reaction:
NONE
Acknowledge:
NONE
Cause:
A fault has occurred while identifying the moment of inertia.
Alarm value (r2124, 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: It is not possible to increase the speed by 10% as the minimum limiting is active.
6: It is not possible to increase the speed by 10% as the suppression (skip) bandwidth is active.
7: It is not possible to increase the speed by 10% as the maximum limiting is active.
8: The torque difference after the speed setpoint step is too low in order to be able to still reliably identify the moment
of inertia.
9: Too few data to be able to reliably identify the moment of inertia.
10: After the setpoint step, the speed either changed too little or in the incorrect direction.
11: The identified moment of inertia is not plausible.
