OUTPUTS
NOTE: The installation of this motor control must conform to area and local electrical codes. Refer to page
9 before you begin wiring.
Speed Command Out
(J3 pins 1, 2)
SPEED COMMAND OUT is an isolated analog
output signal that is sent to the motor drive to control
the speed of the motor. Wire the SPEED COMMAND
OUT into the speed signal input of the drive. If the
motor drive has a potentiometer speed control,
remove the potentiometer connections and wire the
SPEED COMMAND OUT output to the potentiometer
wiper point. The CX–1010's Isolated Common
should always be connected to the drive common.

Zero Speed
(J2 pin 2)
Digital Output 0
The ZERO SPEED output is activated (driven low) when the feedback is less than or equal to zero speed,
as determined by the value that you enter in the Zero Speed Alarm Control Parameter (CP-270).
Hi Speed Alarm
(J2 pin 3)
Digital Output 1
The HI SPEED ALARM output is activated (driven low) if the system's speed is greater than the speed alarm
value that you enter in the CMPR1 Val Control Parameter (CP-292), See Figure 29.
Lo Speed Alarm
(J2 pin 4)
Digital Output 2
The LO SPEED ALARM output is activated (driven low) if the system's speed is lower than the value that
you enter in the CMPR2 Val Control Parameter (CP-293). See Figure 29.
