OUTPUTS
NOTE: The installation of this motor control must conform to area and local electrical codes. Refer to page
9 before you begin wiring.
Unwind Control Output
(J8 pins 1, 2)
Unwind Control Output is an isolated analog output
signal that is sent to the motor drive to control the
speed of the motor. Wire the Unwind Control Output
into the speed signal input of the drive. If the motor
drive has a potentiometer speed control, remove the
potentiometer connections and wire the Unwind
Control Output to the potentiometer wiper point. The
CX-1102's Isolated Common should always be
connected to the drive common.
