The Axis Module provides terminating points for the motor power, thermal
sensor and brake. Axis module wiring is identical for all module ratings.
Refer to Figure 5B.21 and the paragraphs that follow for detailed

Motor Wiring
Allen-Bradley 1326-CPB1xxx cables must be used for connection to the
motor. The motor wiring size is determined by the continuous and
overload current requirements (RMS Duty Cycle), NEC and local codes. In
general, motors operated with the 1394 should not require wire sizes larger
than those accepted by the motor terminal blocks. In addition, the motor
leads must be twisted throughout their entire length to minimize radiated
electrical noise. The maximum motor wire sizes that the 1394 Axis Module
terminal block will accept are dependent upon axis module selection (see
your 1394 users manual).
