This error only occurs during sensorless positioning of synchronous motors.
Description:
It was impossible to determine initial position of rotor.
Rotor was moving during transient oscillation of rotor position estimation.
An error occurred when rotor angles determined before and after commutation adjust were compared.
Determined commutation offset is wrong – and/or – rotor was moving during saturation method.
Check whether parameter values of sensorless positioning of synchronous motors correspond to specification.
Make sure that rotor does not turn during commutation process.
Make sure that rotor does not turn during commutation process. – and/or – Adjust parameter values of ‘P-0-0506, Amplitude for angle acquisition’, ‘P-0-0507, Test frequency for angle acquisition’ and ‘P-0-0517, Commutation: required harmonics component’ or start search mode. – and/or – Check whether parameter values of sensorless positioning of synchronous motors correspond to specification.
