Stator Wiring

The locked rotor stator current is equal to the amplifiers continuous rating and for either low
speed or locked rotor conditions the stator must withstand this continuous rating. Derating the
stator wiring for three phase operation should not be done.

Model

Locked Rotor

MPA-80-231

80 Amps

A

(ground) terminal is supplied and should be connected to earth ground.

If shielded cable is not used, it is recommended that the RST and GND wires be twisted.

NOTE

The resolver feedback wiring should not
be run adjacent to the RST motor wiring.
