Lead Sync Absent
(J2 pin 5)
Digital Output3
The Lead Sync Absent output is activated (driven low) when the Lead Sync Pulse is absent. See Figure 32.
Foll Sync Absent
J2 pin 6)
Digital Output 4
The Foll Sync Absent output is activated (driven low) when the Follower Sync Pulse is absent. See Figure 32.
Batch Done
J2 pin 7)
Digital Output 5
The Batch Done output is activated (driven low) when the CX-1200's internal batch counter reaches the batch count that
you enter in the Cntr1Trig (CP-420). See Figure 32.
Fwd/Rvs
(J2 pin 8)
Digital Output 6
The Fwd/Rvs is activated (driven low) when the CX-1200 commands a forward direction to the motor drive. The Fwd/
Rvs output is deactivated (driven high) when the CX-1200 commands a reverse direction to the motor drive. See Figure
32.
Drive Enable
(J2 pin 9)
Digital Output 7
The Drive Enable output is activated (driven low) when the CX-1200 signals a run command to the motor drive. The
Drive Enable output is driven high (relay deactivated) after Power Up and at the completion of F-Stop. See Figure 32.
NOTE: The Digital Outputs are open-collector relay drivers. For specification details, see Appendices: Appendix A .
Use an external DC power supply to power the relays. Free-wheeling diodes are incorporated internally in the
CX-1200 and do not need to be added externally.
