Control Output
(J3 pins 1, 2)
Control Output is an isolated analog output signal that
is sent to the motor drive to control the speed of the
motor. Wire the 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 Control Output to the
potentiometer wiper point. The CX-1200's Isolated
Common should always be connected to the drive
common.
OUTPUTS
NOTE: The installation of this motor control must conform to area and local electrical codes. Refer to page
9 before you begin wiring.
NOTE: All Digital Outputs are activated via the PLC and so are subject to the active PLC program.
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-332). See Figure 32.
Hi/Low 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-388), 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-389). See Figure 32.
Sync Alarm
(J2 pin 4)
Digital Output 2
The Sync Alarm output is activated (driven low) the Lead and Follower sync pulses are not syncronized. See Figure32.
