vehicles, military, medical treatment, combustion and recreation, or equipment in contact with food and
beverages, emergency stop circuits, clutch and brake circuits in press applications, safety equipment or
other applications unsuitable for the standard specifications described in the product catalog.
3.An application which could have negative effects on people, property, or animals requiring special safety
analysis.
4.Use in an interlock circuit, which requires the provision of double interlock for possible failure by using a
mechanical protective function, and periodical checks to confirm proper operation.

2. Product Outline
2.1 Product features
The followings are the main functions of this controller:
Electric Actuator Control
Positioning operation and Pushing operation, at a specific speed and force, of the electric actuator
are possible by controlling the Step motor (24 VDC servo).
Specified force operation
Control the pushing force (or the pressing force) of the electric actuator.
Separated power supply
The power supply is separated into the drive power and the control power. Therefore, even when
the drive power is off, if the control power is on, the position information from the encoder will be
maintained and the serial communication and parallel I/O control are still available.
Return to origin
Return the electric actuator to the home position by sending a single signal to a dedicated
terminal.
Alarm detection function
Automatically detect the abnormal conditions and output the appropriate alarm signal via the
serial interface and parallel I/O. The alarm information (up to the last 8 alarms) will be recorded
into the memory in the controller.
64 step data
Control the electric actuator according to the step data specified by the input of parallel I/O.
It is possible to setup various parameters for each operation pattern.
Area output
The area output terminal will be activated if the electric actuator position is within the range
specified by “Area 1” and “Area 2” in the step data.
Data input method
It is possible to perform parameter setup, status monitoring, trial run and alarm reset via the serial
communication with a PC installed with the controller setting kit or the teaching box.
Easy mode and Normal mode
There are two available modes for the controller setting kit and the teaching box. In Easy mode,
you can start the operation by only setting the speed, position, etc. In Normal mode, further
detailed setup can be performed.
Caution
Please keep this manual safe for future use. It will be necessary to refer to this manual along with the
operation manuals for other electric actuators, teaching box, and controller setting kit at installation and
fault finding.
Keep this operation manual accessible for reference.

Problems
If the LED [PWR] lights in green, the controller is in the normal condition.
However, if the LED [ALM] lights in red, the controller is in the alarm (error) condition.
Caution
In case of alarm (error) condition:
Connect a PC or the teaching box to the CN4 serial I/O connector and check the details of the alarm.
Then, remove the cause of the error referring to the “12. Alarm Detection”
Please refer to the manuals of the controller setting software or the teaching box for details of the
alarms.

3.4 How to install
(1) How to install
The controller can be direct mounted using screws or mounted on a DIN rail.
The followings are the descriptions on how to install each type:
1) Screw mount type (LECP6□□-□)2) DIN rail mount type (LECP6□□D-□)
(Installation with two M4 screws) (Installation with the DIN rail)
(2) Ground wire connection
Place the grounding cable with crimping terminal and toothed washer as shown below and tighten the
screw.
Caution
The M4 screw, cable with crimping terminal, and toothed washer should be obtained separately.
Ground the controller to shield it from electric noise.
If higher noise resistance is required, ground the 0V (signal ground).
When grounding the 0V, avoid flowing noise from the ground to the 0V.

Caution
The earthling should be the dedicated grounding point. It should be a functional ground with less than
100 Ω resistance.
The cross section of the grounding wire should be greater than 2mm2.
The ground point should be near this controller to make the wire length shorter.
Recommended Functional grounding Not Recommended grounding
(3) Installation location
Select the size and the installation style so that the surrounding temperature of the controller is 40oC or
less.
Mount the controller vertically on the wall with the space allowed as shown in Fig. 1.
As shown in Fig. 2, establish the construction so that the connectors can be connected and
disconnected.
Enough space must be allowed around the controller so that the operating temperature of the controller
stays within the specification range.
Avoid mounting the controller near a vibration source, such as a large electromagnetic contactor or
circuit fuse breaker on the same panel.
Fig.1 Fig.2 Cover (the housing)
Caution
If the mounting surface of the controller is distorted or not flat, excessive force may be applied to the
housing, etc. causing malfunction.
Mount this product on a plane flat surface.
