4. Description of Operating Functions
* T1: Set T1 to 0 msec or more in consideration of the scan time of the host controller.
[Operational description]
[1] Perform positioning operation to position 1 (100.00 mm).
[2] Upon completion of positioning to position 1, the position complete signal (PEND) will become “1.”
The zone signal (PZONE) will also become “1.”
After changing the position number from 1 to 2, set the start signal (CSTR) to “1.”
[3] When movement starts, (PEND) will change from “1” to “0” and the moving signal (MOVE) will change from
“0” to “1.” After confirming that (MOVE) has become “1,” set the start signal (CSTR) to “0.”
[4] When the actuator has moved only 50 mm, (PEND) will become “1” and (MOVE) will become “0” again. At
this time, the PLC counts the first time of movement.
Then, set the (CSTR) for the second 50 mm movement to “1.”
[5] Repeat the operations of [3] and [4].
The PLC checks the zone signal (PZONE) status when positioning has been completed and judges that the
current position is the last work position if the signal has become “0.”
If the number of counts on the PLC side does not agree with the zone signal status, it is assumes that the signal
timing is not synchronized.
