Calculation of the offset

The wiring must be done according to the layout of the coil units. The offset must be determined in order to do this. The offset specifies the number of coils by which the rotary field is shifted in the second motor. The wiring of the motors can be determined with the help of the offset and the table in the section entitled Layout of the wiring.


The offset is calculated using the following equation:

Offset = (PDM1M2 / 16) MOD 3


Calculation of the offset for example 1:

Offset

= (304 / 16) MOD 3

 

= 19 MOD 3 = 1


Calculation of the offset for example 2:

Offset

= (272 / 16) MOD 3

 

= 17 MOD 3 = 2
