Chapter 4 Parameters

This function is used for searching magnetic field 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 field orientation.
