代码 207412: <location>Drive: Commutation angle incorrect (motor model)

Message value: Drive object: SERVO, VECTOR Reaction: ENCODER (NONE, OFF2) Acknowledge: IMMEDIATELY SINAMICS-Alarms Cause: An incorrect commutation angle was detected, that c an result in a positive coupling in the speed controller. Possible causes: - the motor encoder is incorrectly adjust ed 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. - the motor encoder speed signal is faulted. - the control loop is instable due to incorrect parameterization. Fault value (r0949, interpret decimal): SERVO: 0: The comparison of the pole position angle from the encoder and the motor model resulted in an excessively high value (> 80 ° electrical). 1: VECTOR: 0: The comparison of the pole position angle from the encoder and the 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). - correctly set the motor stator resistance, ca ble resistance and motor-stator leakage inductance (p0350, p0352, p0356). - increase the changeover speed for the motor model (p1752). The monitoring is completely de-activated for p1752 > p1082 (maximum speed) Note: For High Dynamic Motors (1FK7xxx-7xxx), for applic ations with a higher current, if necessary, the monitoring should be disabled.
