Wiring the drive
In a traditional wiring diagram the drive is connected in a so-called star connection. To
make sure that the drive does not lose any torque above 60Hz, it needs to be connected in
a delta configuration. The next figure shows how this can be done. To reverse the
configuration, interchange the supply leads L1 and L2.
A
Motor winding
B
Motor terminal board
C
Supply leads
D
Delta-connected, low voltage
E
Star-connected, high voltage
