Recommended Cable Configurations: Driver to Motor
Cable length, wire gauge and power conditioning devices play a major role in the performance
of your Driver and Motor.
NOTE: The length of the DC power supply cable between the Driver and the Motor should not
exceed 50 feet.
Example A demonstrates the recommended cable configuration for the Driver to Motor cabling
under 50 Feet long.
Correct AWG wire size is determined by the current requirement plus cable length. Please see
the Driver to Motor Cable AWG Table in this Appendix.
If cabling of 50 feet or longer is required, the additional length can be gained by adding
Common Mode Line Filters (2x)
*L ≈ 0.5 MH
* 0.5 MH is a typical starting point for the Common Mode Line Filters. By increasing or
decreasing the value of L you can set the drain current to a minimum to meet your
requirements.
