Motor wiring (U, V, W)

The three phase wires should be close to the same length and bundled together
as they run between the controller and the motor. The cable lengths should be
kept as short as possible. Use high quality copper lugs and observe the recom-
mended torque ratings. For best noise immunity the motor cables should not
run across the center section of the controller. In applications that seek the
lowest possible emissions, a shield can be placed around the bundled motor
cables and connected to the
will readily pass the emissions standards without a shield. Low current signal
wires should not be run next to the motor cables. When necessary they should
cross the motor cables at a right angle to minimize noise coupling.
