Remedy:
- correct the motor data.
- check the motor configuration.
- correct the current limits (p0640, p0323).
- if required, use a larger motor module.
F07412
Drive: Commutation angle incorrect (motor model)
Reaction:
ENCODER (NONE, OFF2)
Acknowledge:
IMMEDIATELY
Cause:
An incorrect commutation angle was detected, that can result in a positive coupling in the speed controller. The com-
parison of the rotor position angle from the encoder and the motor model resulted in an excessively high value (> 80
° electrical).
- the motor encoder is incorrectly adjusted with respect to the magnet position.
- the motor encoder is damaged.
- the angular commutation offset is incorrectly set (p0431).
- data to calculate the motor model has been incorrectly set (p0356 (motor-stator leakage inductance) and/or p0350
(motor-stator resistance) and/or p0352 (cable resistance).
- the changeover speed for the motor model is too low (p1752). The monitoring function only becomes effective
above the changeover speed.
Remedy:
- if the encoder mounting was changed - re-adjust the encoder.
- replace the defective motor encoder.
- correctly set the angular commutation offset (p0431).
- correctly set the motor stator leakage inductance, motor-stator resistance and cable resistance (p0356, p0350,
p0352).
- increase the changeover speed for the motor model (p1752).
F07413
Drive: Commutation angle incorrect (rotor position ID)
Reaction:
OFF2 (NONE)
Acknowledge:
IMMEDIATELY
Cause:
An incorrect commutation angle was detected, that can result in a positive coupling in the speed controller. The com-
parison of the rotor position angle from the encoder and from the rotor position identification routine has resulted in
an excessively high difference (> 45 ° electrical).
- the angular commutation offset is incorrectly set (p0431).
- the motor encoder is incorrectly adjusted with respect to the magnet position.
- the motor encoder is damaged.
- the rotor position identification routine does not function correctly.
Remedy:
- correctly set the angular commutation offset (p0431).
- re-adjust the motor encoder after the encoder has been replaced.
- replace the defective motor encoder.
- check the rotor position identification routine. If the rotor position identification routine is not suitable for this motor
type, then disable the plausibility check (p1982 = 0).
F07414
Drive: Encoder serial number changed
Reaction:
ENCODER (NONE, OFF2)
Acknowledge:
IMMEDIATELY
Cause:
The serial number of the motor encoder of a synchronous motor has changed. This means that it may be necessary
to re-calibrate/re-adjust the commutation angle.
- an encoder was replaced.
- re-commission a build-in motor or third-party motor.
- the firmware was updated to a version that checks the encoder serial number.
Remedy:
Calibrating/adjusting the commutation data in p0431. The calibration/re-adjustment can be automatically initiated
using a rotor position identification routine with p1990 = 1.
If calibration/adjustment is not required, then the serial number can be directly transferred using p0440 = 1.
N07415 (F)
Drive: Commutation angle offset transfer running
Reaction:
OFF2
Acknowledge:
NONE
Cause:
The angular commutation offset was automatically determined using p1990 = 1.
This fault causes the pulses to be cancelled - this is necessary to transfer the angular commutation offset to p0431.
See also: p1990
Remedy:
The fault can be acknowledged without any additional measures.
