- 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.
- pole position identification might have calculated an incorrect value when activated (p1982 = 1).
- the motor encoder speed signal is faulted.
- the control loop is instable due to incorrect parameterization.
Fault value (r0949, decimal interpretation):
SERVO:
0: The comparison of the pole position angle from the encoder and motor model resulted in an excessively high value
(> 80 ° electrical).
1: -
VECTOR:
0: The comparison of the pole position angle from the encoder and motor model resulted in an excessively high value
(> 45 ° electrical).
1: The change in the speed signal from the motor encoder has changed by > p0492 within a current controller clock
cycle.
Remedy: - if the encoder mounting was changed - re-adjust the encoder.
- replace the defective motor encoder.
- correctly set the angular commutation offset (p0431). If required, determine using p1990.
- correctly set the motor stator resistance, cable resistance and motor-stator leakage inductance (p0350, p0352,
p0356).
Calculate the cable resistance from the cross-section and length, check the inductance and stator resistance using
the motor data sheet, measure the stator resistance, e.g. using a multimeter - and if required, again identify the val-
ues using the stationary motor data identification (p1910).
- increase the changeover speed for the motor model (p1752). The monitoring is completely de-activated for p1752
> p1082 (maximum speed).
- with pole position identification activated (p1982 = 1) check the procedure for pole position identification (p1980)
and force a new pole position identification procedure by means of de-selection followed by selection (p1982 = 0 ->
1).
Note:
For High Dynamic Motors (1FK7xxx-7xxx), for applications with a higher current, if necessary, the monitoring should
be disabled.
F07413 Drive: Commutation angle incorrect (pole position identification)
Message value: -
Drive object: SERVO_S110-CAN, SERVO_S110-DP, SERVO_S110-PN
Reaction: ENCODER (NONE, OFF2)
Acknowledge: IMMEDIATELY
Cause: An incorrect commutation angle was detected that can result in a positive coupling in the speed controller.
Within the pole position identification routine (p1982 = 2):
- a difference of > 45° electrical to the encoder angle was determined.
For VECTOR, within the encoder adjustment (p1990 = 2):
- a difference of > 6 ° electrical to the encoder angle was determined.
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 pole position identification routine. If the pole position identification routine is not suitable for this motor
type, then disable the plausibility check (p1982 = 0).
F07414 (N, A) Drive: Encoder serial number changed
Message value: -
Drive object: SERVO_S110-CAN, SERVO_S110-DP, SERVO_S110-PN
Reaction: ENCODER (NONE, OFF2)
Acknowledge: IMMEDIATELY
Cause: The serial number of the motor encoder of a synchronous motor has changed. The change was only checked for
encoders with serial number (e.g. EnDat encoders) and build-in motors (e.g. p0300 = 401) or third-party motors
(p0300 = 2).
Cause 1:
The encoder was replaced.
