Chapter 5 Operation
5.10 ELECYLINDER Operation

ME0392-4C
[2] Control Using SEL Program
[Operation image]
(1) With using the SEL program, input the movement command signals to an EC connection
unit. (Forward or backward)
(2) Input the movement signal from EC connection unit to each unit of ELECYLINDER.
(3) ELECYLINDER units start moving.
(4) A position detection signal gets output from ELECYLINDER. (Forward end or backward
end)
(5) The position detection signal gets output from EC connection unit to PLC.
ELECYLINDER continues its operation while a movement command signal (ST0/ST1) is on, and
a position detection signal (LS0/LS1) turns on after the operation is complete.
If the movement command signal gets turned off before the operation completes, the operation
gets cancelled and an actuator decelerates and stops.
The same even applies to the home return
operation.

5.10.4 Input and output signals and features of EC connection unit
There are the automatic assignment and fixed assignment in RSEL and the details are as follows.
● Automatic Assignment: Assignment in order of I/O slot and option unit
● Fixed Assignment: Top port numbers of I/O slot and option unit are to be set
Individual setting for each option unit is not available.
There are as described below for the option units and assignment should be made in order close
to RSEL.
● PIO/SIO/SCON Extension unit
● PIO unit
● EC Connection unit
Caution
An EC connection unit should occupy 4 points of input and 4 points of output for 1 axis of
ELECYLINDER unit and occupies 16 points of input and 16 points of output for 4 axes.
It occupies for 4 axes (16 points) even if not all of the 4 axes are connected.
