2.12 Notes on commissioning linear motors
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.
