CONTREX CX-1200 - Manual (Page 37)

2-23
Lead Sync Absent
(J2 pin 5)
Digital Output 3
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.
