7. Operation of MEC Controllers
Operation Pattern
PMEC and AMEC controllers offer two operation patterns.
The table below gives an overview o the operation specification of each pattern. [For the setting
methods, refer to the sections on initial setting and stop position setting.]
Operation pattern Description

How to connect motorized
cylinder
Stopping at
2 points
(2-point
positioning)
Movement by 1 input
betwe
en 2 po
ints
[Single-solenoid mode]
You can move the actuator
between 2 points using the same
control you would normally use
with an air cylinder.
You can set the positions of the
end point and start point.
You can specify the moving
speed and
acceleration/deceleration. You
can also specify push-motion
operation. The actuator moves to
the end point when the ST0 turns
ON, and returns to the start point
when the signal turns OFF.

Stopping at
3 points
(3-point
positioning)
Movement by 2 input
betwe
en 3 po
ints
[3-point positi
oning]
You can move the actuator
between 2 points using the same
control you would normally use
with an air cylinder.
You can set the positions of the
end point and start point.
You can set the position of an
intermediate point and perform
positioning to the intermediate
point.
You can specify the moving
speed and
acceleration/deceleration. You
can also specify push-motion
operation. The actuator moves to
the end point when the ST1 turns
ON, and moves to the start point
when the ST0 turns ON.
[Intermediate movement mode,
both ON]
When both the ST0 and ST1 are
turned ON, the actuator will
position to and stop at an
intermediate point.
When both the ST0 and ST1 are
turned OFF, the actuator will stop
in the middle of movement.
[Intermediate movement mode,
both OFF]
When both the ST0 and ST1 are
turned OFF, the actuator will
position to and stop at an
intermediate point.
When both the ST0 and ST1 are
turned ON, the actuator will stop
in the middle of movement.
(Note) The air cylinder circuits are drawn with symbols of signals corresponding to those used by
PMEC/AMEC controllers. For details on signals, refer to the “PMEC/AMEC Operation Manual.”
