Recording the phase voltage and the pole position angle using an oscilloscope
1. Switch the drive line-up into a no-current condition.
2. After the DC link has completely discharged, disconnect the motor cables from the
converter.
If motors are connected in parallel, then disconnect them.
3. Form an artificial neutral point using 1 kΩ resistors (for a parallel connection, for each
motor).

4. Move the drive with a constant speed in the positive direction. The direction of the drive
rotation is positive if the primary section moves relative to the secondary section in the
opposite direction to the cable outlet direction (see also the "Determining the positive
direction of the drive (Page 197)" figure).
Checking the phase sequence
For the positive direction of the drive, the phase sequence must be as follows:
EMF phase U - EMF phase V - EMF phase W
