Part 3 Positioner Mode
* To perform push-motion or interpolation operation, turn ON the applicable input signal before turning
ON the start input signal. Turn the operation signal OFF after the start input signal has turned OFF.
* While the actuator is moving to the target position, only the pause or cancellation input is accepted.
The servo cannot be turned off even if the servo ON input signal is turned OFF. (The servo can be
turned off only when the positioning complete output signal is ON.)
* While the start input signal is ON, the positioning complete output signal will not turn ON even after the
actuator physically completes moving to the target position. Therefore, always turn OFF the start input
signal ([4]) to detect the completion of positioning.
* As for the positioning complete output signal and push-motion complete output signal, they will not be
output until the start signal turns OFF (based on the I/O control handshake rules).
* For the actuator to operate upon start signal input, the servo ON input signal must be ON. If the servo
ON input signal is OFF, these operation commands will not be accepted. Note, however, that only the
commands will be ignored and no error will generate.
