5. Operation of MEC Related Controllers
272
Operation Pattern
PMEC and AMEC and ERC3 (MEC mode) controllers offer two operation patterns.
The table below gives an overview of the Operation specification of each pattern. [For the
setting methods, refer to the sections on initial setting and stop position setting.]

How to connect motorized

Stopping at
2 points
(2-point
positioning)
Movement by 1 input between
2 points
[
Sin
g
le-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
OF F.
Stopping at
3 points
(3-point
positioning)
Movement by 2 input between 2 points
[Double-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 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.
Movement by 2 input between 3
points

PMEC, AMEC and ERC3 (MEC mode) controllers. For details on signals, refer to the
