Note
Direction of motor rotation
If the motor was connected with an incorrect direction of phase rotation, it can be corrected
without replacement of the phase sequence via p1821 (phase rotation direction reversal).
The correct phase sequence must be observed in both sub-cabinets when connecting
cabinet units in parallel, since it is not possible to use converter functions to correct different
phase sequences in the two sub-cabinets at a later stage.
For motors that can be star-connected or delta-connected, it must be ensured that the
windings are interconnected consistent with the operating voltage indicated on the type plate
or in the motor documentation. Make sure that the winding insulation of the connected motor
has sufficient insulation strength to meet the requirements for converter operation.
