0: No function
1: ABZ
7: PWM pulse
Detection of the magnetic pole: Setting 1: The AC motor drive will output short circuit to detect the
position of the magnetic pole. At this moment, the motor will generate a little noise.

A Pulse Generator (PG) or encoder is used as a sensor that provides a feedback signal of the motor
speed. This parameter defines the number of pulses for each cycle of the PG control (PPR).
