Automatic commutation: Incorrect Commutation Adjustment
  • 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.
