Motor and Drive Power Wiring
In accordance with NEC, the power wiring size should be based on the 30
minute overload rating of the applicable motor. The user must determine if
national or local codes specify other requirements. All power wiring should
be terminated to the bolt or screw terminals on the drive and motor using
ring type terminal lugs.
ATTENTION: To guard against the hazard of personal injury
or damage to equipment, the interconnections to the motor and
feedback device must be made as explained in this chapter.
Failure to do so could cause loss of motor control and/or severe
oscillation of the motor shaft.

The size of the power terminal connections on the drive for incoming AC
line power and motor power terminations is shown below.

To minimize radiated PWM noise, the individual motor phase wires must
be part of a single multi-conductor cable or run very close together. The
motor cables should be contained in grounded metal conduit or raceways.
