The Interconnect Drawing presented in Appendix B provides typical
interconnection wiring for the 1391-DES AC Servo Drive. Typical control
logic circuitry (starting and stopping), motor interconnections and
grounding techniques are shown.
Please note that the drive circuit breaker (MCB) is not designed or intended
to meet branch circuit protection requirements. The circuit breaker protects
the DC bus supply, input rectifier and power circuitry against overcurrents.
Motor Wiring
The motor wiring size is determined by the continuous and overload
current requirements (RMS Duty Cycle), NEC and local codes. In general,
motors operated from the following drives would not require wire sizes
larger than those accepted by TB5, but codes must be followed. In
addition, the motor leads must be twisted throughout their entire length to
minimize radiated electrical noise. Allen-Bradley 1326 cables (or
equivalent type) must be used. The maximum motor wire sizes that the
1391-DES drive will accept are shown in Table 7.A.
