Part 3 Positioner Mode
5.3 Movements through Positions
Timings of how the actuator moves through positions are illustrated below.
Timing Chart of Movement through Positions (Positioner Mode)
T1: Time after a position number signal is input until the start signal can be input (30 msec or more)
T2: Start signal input (30 msec or more)
T3: Time after the start signal turns ON until the positioning complete output signal turns OFF
(60 msec or less)
T4: Time after the last positioning complete output signal turns ON until the next start signal can
be input (50 msec or more)
Operate the actuator to move through positions by following the procedure explained below.
* Confirm that the positioning complete output signal is ON.
[1] Change the previous position number input (BCD input) to a different position number.
[2] Turn ON the start input signal (continuously for 30 msec or more (T2)).
[3] Turn OFF the start input signal.
[4] Wait for T3 from [2].
[5] Confirm that the positioning complete output signal is ON.
Repeat steps [1] through [5] sequentially.
* To perform interpolation operation, turn ON the interpolation setting input signal 30 msec before turning
ON the start input signal. Turn OFF the interpolation signal after the start input signal has turned OFF.
* The positioning complete output signal turns ON upon completion of positioning movement, regardless
of whether the start input signal is ON or OFF.
* Take note that the time after the start signal turns ON until the position complete output turns OFF is
60 msec or less, which is different from 15 msec or less when the DS-S-C1 controller is used.
Caution: Unlike in other modes, the pause input and cancellation input are contact-A input signals
(always OFF). The alarm output is also a contact-A output signal (always OFF) unlike in
other modes.
