A variety of cable types are acceptable for
variable speed controller installations. For many
installations, unshielded cable is adequate,
provided it can be separated from sensitive
circuits. As an approximate guide, allow a
spacing of 1 meter (3.3 feet) for every 10 meters
(33 feet) of unshielded length. If you cannot
separate motor cables from sensitive circuits, or if
you must run motor cables from multiple
controllers (more than three) in a common
conduit or cable trays, shielded motor cable is
recommended to reduce system noise.
Motor cables should be four-conductor with the
ground lead and shield (if using shielded cable)
connected to the controller ground terminal and
the motor frame ground terminal.
Installations with long motor cables may require
the addition of output reactors to reduce voltage
reflections at the motor, and reduce cable
charging current. Capacitive charging of long
motor cables may draw current in excess of the
controller rating. The controller should be
installed as close to the motor as possible.
Important: Both Reflected Wave and Capacitive
Current Considerations need to be taken into
account when determining motor cable lengths.
Refer to Table 2.D and Table 2.E .
