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:
- check the encoder connection. If required, replace the encoder.
For fault value = 6:
- check the connection assignment of the encoder cable. Adapt the polarity (p0410).
For fault value = 7:
- adapt the pulse number (p0408).
For fault value = 8:
- check the encoder connection and encoder cable. It is possible that there is a problem associated with the ground
connection.
- reduce the dynamic response of the speed controller (p1460, p1462 and p1470, p1472).
Note:
The encoder test can be switched out (disabled) using p1959.0.

Drive: Rotating measurement saturation characteristic
Message class:
Error in the parameterization / configuration / commissioning procedure (18)
Reaction:
OFF1 (NONE, OFF2)
Acknowledge:
IMMEDIATELY
Cause:
A fault has occurred while determining the saturation characteristic.
Fault value (r0949, interpret 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 high.
Remedy:
For fault value = 1:
- the total drive moment of inertia is far higher than that of the motor (p0341, p0342).
De-select rotating measurement (p1960), enter the moment of inertia p0342, re-calculate the speed controller p0340
= 4 and repeat the measurement.
For fault value = 1 ... 2:
- increase the measuring speed (p1961) and repeat the measurement.
For fault value = 1 ... 4:
- check the motor parameters (rating plate data). After the change: Calculate p0340 = 3.
- check the moment of inertia (p0341, p0342). After the change: Calculate p0340 = 3.
- carry out a motor data identification routine (p1910).
- if required, reduce the dynamic factor (p1967 < 25 %).
For fault value = 5:
- the speed setpoint (p1961) is too high. Reduce the speed.
For fault value = 6:
- adapt the speed setpoint (p1961) or minimum limiting (p1080).
For fault value = 7:
- adapt the speed setpoint (p1961) or suppression (skip) bandwidths (p1091 ... p1094, p1101).
For fault value = 8:
- adapt the speed setpoint (p1961) or maximum limit (p1082, p1083 and p1086).
