Detection of the magnetic pole:
Setting 1: The brushless DC motor drive will output short circuit to detect the position of the
magnetic pole. At this moment, the motor will generate a little noise.
Setting 2: The brushless DC motor drive will detect the position of the magnetic pole by the
UVW signal of encoder.
Setting 3: The brushless DC motor drive will detect the position of the magnetic pole by the
sine signal of encoder.

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.
