Batch Reset
(J7 pins 2,3)
Digital Input 9
Batch Reset is a momentary input. When it is closed, the CX-
1200 resets the internal batch counter to zero. The default
internal batch counter is "Cntr1 Cnt" (CP-421) a PLC event
counter.
Re-Learn
(J7 pins 4, 3)
Digital Input 10
Re-Learn is a momentary input. When it is closed, the CX-
1200 initiates a Re-Learn process in one of the sync follower
modes. For any other mode of operation, the Re-Learn input
will cause the position information to be reset to zero and the
job space information to be reset to the maximum job space
until the CX-1200 Re-Learns the job space information.
Open Loop
(J7 pins 5, 3)
Digital Input 11
Open Loop is a maintained input. When it is closed (Open
Loop), it the Control Output is adjusted in response to the
setpoint changes only and feedback and error are ignored.
When it is open (Closed Loop), the control algorithm adjusts
the Control Output to reduce the error to zero.
