For a positive traversing direction, the phase sequence must be U-V-W. The direction of the

drive is positive if the primary section moves relative to the secondary section in the opposite

direction to the cable outlet direction.

Determining the commutation angle using an oscilloscope

Once the oscilloscope has been connected, the drive must first pass the zero mark so that

fine synchronization can be carried out.

The angular, commutation offset can be determined by measuring the EMF and normalized

electrical pole position via an analog output.
