The table shows the number of poles for normal speed ranges of various motor types. Define motors designed for other frequencies separately. The
motor pole value is always an even number, because it refers to the total number of poles, not pairs of poles. The frequency converter creates the initial
setting of par. 1-39 based on par. 1-23

When using PM motors, it is recommended to use brake resistors.
Function:
Enter the correct offset angle between the PM motor and the index position (single-turn) of the attached encoder
