11.7.1 Adjustment of the Parameters P0409 to P0412 Based on the Motor Data Sheet
Being in the possession of the motor equivalent circuit data, it is possible to calculate the value to be programmed
in the parameters from P0409 to P0412, instead of using the self-tuning to obtain them.
Input data:
Motor data sheet:
V
