The position complete output will turn ON when the controller becomes ready following the power ON.
To check if the controller is ready, always check if the position complete output is ON.
The actuator will not operate unless the pause input is turned ON.
T1: 6 msec or more; time after selecting/entering a command position until the start input turns ON
(The scan time of the host controller must be considered.)
Caution: [1] When the start signal turns ON, the position complete output will turn OFF.
The start signal must be turned OFF with the confirmation that the position complete output has
turned OFF while the start signal remains ON.
If the start input remains ON as shown below, the position complete output will not turn ON even
when the actuator movement is completed.
[2] Increasing the positioning band allows the position complete signal to turn ON more quickly, and
consequently the next operation in the sequence starts early.
This is an effective means for reducing the tact time, so set an optimal value based on the
overall balance of your system.
