5. Rotate the rotor clockwise, keeping the speed as constant as possible. If you do not
manually rotate the rotor, then observe the subsequent separate description.
6. For all stator segments, measure and check the phase sequence and phase position of
the EMF.
Procedure to rotate the rotor
The procedure depends on the number of Motor Modules and the stator segments
connected in parallel. The following preconditions must be satisfied for the procedures
subsequently described:
● The drive must be correctly connected up
● Reduced controller gain
● Low speed
Procedure for one stator segment for each Motor Module
1. Activate the master drive and deactivate the slave drives (e.g. p840 = 0).
2. Disconnect all slave drives.
3. Carefully note that each rotor movement with respect to the stator - and vice versa -
results in a voltage being induced at the stator segment power connections.
4. Ensure that the conductor ends are open circuit so that you do not create a short-circuit.
5. Rotate the master drive at the control panel.
6. Measure all stator segments of the slave drives one after the other.
7. Reconnect a slave drive.
8. Disconnect the master drive.
9. Rotate a slave drive from the control panel and measure the stator segment of the master
drive.
Procedure for several stator segments connected in parallel for each Motor Module
If one stator segment is sufficient to move the drive, then select the following procedure.
1. Disconnect the parallel connection.
2. Keep the stator segment circuit breaker closed so that the drive can be moved.
3. Open all other circuit breakers.
4. At the master drive, set p306 = 1 - and recalculate the controller data with p340 = 3.
5. Activate the master drive and deactivate the slave drives (e.g. p840 = 0).
6. If necessary, disconnect the remaining stator segments of the master drive and all stator
segments of the slave drives.
