Operation Pattern
The PMEC, AMEC or ERC3 (MEC mode) controller has the 2 operation patterns.
Each of these 6 patterns is described as in the table. Also, the corresponding air cylinder circuit is
described for reference. [Refer to Initial Setting and Stop Position Setting for the setting.]

1-Input, 2-Point Movement
The actuator 2-Point movement
is available using the same
control function as for the air
cylinder.
Backward and forward points
can be determined.
Speed and acceleration settings
in the actuator movement are
available.
The pressing operation is
available.
Set ST0 ON to move to the
backward point and OFF to
return to the forward point.

The actuator 2-Point movement
is available using the same
control function as for the air
cylinder.
Backward and forward points
can be determined.
Setting of intermediate point is
available, and positioning to the
intermediate point is also
available.
Speed and acceleration settings
in the actuator movement are
available.
The pressing operation is
available.
Set ST1 ON to move to the
backward point and ST0 ON to
forward point.
[Both switches ON to move to
intermediate point]
Set both ST0 and ST1 ON to
stop at intermediate point for
positioning.
Set both ST0 and ST1 OFF and
it stops on the way.
[Both switches OFF to move to
intermediate point]
Set both ST0 and ST1 OFF to
stop at intermediate point for
positioning.
Set both ST0 and ST1 ON and it
stops on the way.
