Direction of motor rotation

With induction machines with a clockwise phase sequence (looking at the drive shaft), the

motor must be connected to the cabinet unit as follows.

Table 4- 3 Cabinet unit and motor connection terminals

U2/T1 U

V2/T2 V

W2/T3 W

In contrast to the connection for the clockwise phase sequence, two phases have to be

reversed with a counter-clockwise phase sequence (looking at the drive shaft).

Note

If an incorrect rotating field was connected when the cables were installed, and the rotating

field cannot be corrected by swapping the motor cables, it can be corrected when

commissioning the drive via p1821 (rotating field direction reversal) by changing the rotating

field and thus enabling a direction reversal (see section "Functions, Monitoring and

protective functions / Direction reversal").

With motors that can be operated in a star/delta configuration, the windings must be checked

to ensure that they have been connected properly. Please refer to the relevant

documentation for the motor and note the required insulation voltage for operating the

cabinet unit.
