The direction of rotation can also be reversed via parameter P1820 (see system parameter list on page 66).
Note: If the VSD is reset to factory defaults, parameter P1820 will be reset.
5.3.2 Star or delta connection
The required supply voltage and method of connection are indicated on the motor rating plate. In general, larger
motors (AC 400 / 690 V) are connected in a delta configuration and smaller motors (AC 230 / 400 V) in a star con-
figuration.
