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).
See page 5A-14 for details on resolver cables (1326-CCUxxx).
1326 servo motors have integral thermal protection. This contact must be
connected in the E–Stop string for motor overload protection.
