 This function is used for searching magnetic pole position and only for permanent magnet

motor.

 When it doesn’t have origin-adjustment for encoder (Pr.08-09 is 360.0), it can only ensure that

the motor operation efficiency can be up to 86% of the best efficiency. In this situation, when

the operation efficiency needs to be improved, user can re-power on or set Pr.08-10 to 1 to

get the magnetic pole orientation.
