4.4 Operation in MEC Mode 1 and 2 (Operation with PLC)
There are two types of operation modes in MEC Mode, 2-point stop and 3-point stop, and
2-point stop performs the same operation as of Single Solenoid while 3-point stop possesses a
function of intermediate stop in addition to the operation same as that of Double Solenoid.
ERC3 is controlled with PIO directly in MEC Mode 1 and via PIO Converter in MEC Mode 2,
however, the operation method is the same for both modes. MEC Mode 2 is applicable for
Simple Absolute Type.
In this mode, Quick Teach can be used.
These teaching tools listed below are also able to be used.
(1) MEC PC Software
(2) Touch Panel Teaching
[1] Outline for Operation Patterns and Functions
The settings for the operation patterns and operational conditions are to be established in a
teaching tool. For the details, refer to each instruction manual.
Operation Pattern Overview
Stopping at 2 points
(2-point positioning)
[Single-solenoid mode]
Movement by 1 input
between 2 points
Air cylinder can perform a 2-point movement with
the control same as when operating Single
Solenoid.
You can set the positions of the end point and start
point.
You can specify the moving speed and
acceleration/deceleration.
[Double-solenoid mode]
Movement by 2 input
between 2 points
Stopping at 3 points
(3-point positioning)
[3-point positioning]
Movement by 2 input
between 3 points
Air cylinder can perform a 2-point movement with
the control same as when operating Double
Solenoid.
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.
