2. Product Outline
2.1 Product features
The followings are the main functions of this controller:
●
Electric actuator control
Positioning operation and operation at a specific speed for the electric actuator are possible by
controlling the Step motor (servo 24 VDC).
●
Operation and settings are available with the controller.
Settings can be altered and operation can be run from the controller. Adjustments of the position,
speed, acceleration and test runs are available without the teaching box, PC, and PLC.
●
Power supply separation input
The power input is separated into two systems of motor power supply and control power supply,
and when the control power supply is on while the power supply is off, the parallel I/O control is not
lost without losing the position information of the encoder is possible.
●
Positioning of 12 intermediate points and both stroke end points are possible.
According to the combination of parallel I/O inputs, it is possible to perform positioning operation of
12 points (position numbers 3 to 14 (E)) and positioning operation to the stroke end point (two
points on the end side and the motor side).
In addition, it is possible to set the speed and the acceleration by the switch for each driving
direction.
●
Stroke study
By the stroke study, LEC 6 controller recognizes the possible moving area and registers both
stroke end points automatically.
Just after the controller is delivered and after adjusting the stopper of the electric actuator, the
stroke study must be performed.
Caution
·
When the power is turned on immediately after purchasing the controller, the ALM LED of the
controller blinks in red because the stroke learning has not been performed yet. When stroke learning
is executed, the ALM LED goes out.
· When executing stroke learning, the registration position of all intermediate positions will be changed
so be sure to re-register all intermediate positions (position numbers 3 to 14 (E)).
●
Automatic sequence function of the return to origin position
When power is applied to the LECP2 controller stroke study is performed and return to origin to the
commanded side is possible when the first command of driving to stroke end is executed.
(A dedicated signal for return to origin is not required.)
●
Alarm detection function
Abnormal conditions are self-detected. Alarms are displayed by LED on the controller and
abnormal conditions are output to the parallel I/O terminal.
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.

(4) Power ON alarm (error)
Supply 24 VDC power supply.
Controller
Under normal conditions, the LED [PWR] on the front of the controller changes from a flashing to a
solid light.
The servo will be turned ON if the conditions are normal.
When the LED [ALM] on the front of the controller is ON red, an alarm is generated.
When the power is supplied to the controller just after it is delivered, ALM LED of the controller flashes
in red because Stroke study is not completed.
Therefore, in this case, it is necessary to perform Stroke study.
Caution
If an alarm is generated, check the content of the alarm using the 7-segment LED on the controller or
I/O output, and eliminate the cause while referring to section
“11. Alarm Detection”
.
(5) Stroke study
The stroke study is performed with the buttons and the switches on the controller.
A stroke study of the controller must be performed immediately after purchase or adjustment of the
electric actuator stopper.
Refer to
“7.1(3) Stroke study”
for details.
(6) Registering of the stopping position
The stopping position, speed and acceleration and deceleration are registered with the buttons and
switches on the controller. Refer to
“7.1(7) Registering of the intermediate position”
for details.
(7) Operation check
The operation of the electric actuator is tested by the test run.
The test run is performed with the buttons and the switches on the controller.
Refer to
“7.1(4) Test run”
for details.
(8) The operation of the electric actuator
Change the mode to auto mode using the controller switch. Electric actuator can be operated by
external equipment (PLC, etc.). Refer to
“9. Operation instruction”
for details.

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 short.
The controller case mounting is connected to 0 V of the power supply.
Recommended Functional grounding Not Recommended grounding
(3) Installation location
Select the size and the installation style so that the ambient temperature around the controller is 40
o
C or less.
Mount the controller vertically on a 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
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.

5.2 Wiring of power supply cable
Referring to (1) to (4), connect the power supply cable included in accessories to the controller input
power supply 24 VDC and insert it to the controller CN1 power supply connector.
(1) Wiring of the power supply
Connect the positive side (+) of the controller input power supply 24 VDC to the C24V and M24V
terminals of the power supply cable, and connect the negative side (-) to the 0V terminal.

(2) Wiring of the lock release
Install an unlocking switch for adjustment or recovery during an emergency of the electric actuator with
lock. The switch (24 VDC, Contact capacity: 0.5A or more) should be obtained separately.
One terminal of the lock release switch should be connected to the 24 VDC power supply and the
other should be connected to the BK RLS terminal. When this is switched on, the lock will be released
forcibly.
Power supply cable Controller input power supply
Switch for forced unlocking
Caution
If the electric actuator is a non-lock type, it is not necessary to wire the BK RLS terminal.
Do not supply power to the BK RLS (lock release) during normal operation.
The 24 VDC supply to the BK RLS (lock release) is only required for the adjustment and the recovery
in the emergency.
- STOP command (CN4 14pin STOP) is turned ON and Servo is turned OFF.
- When the control power supply (C24V) is shut off.
(3) Stop the power supply for the motor
If it is necessary to shut off the power supply for the motor from outside, connect the relay between the
input power supply for the controller 24 VDC and the power supply plug for the controller M24V.
(Refer to the wiring diagram in the next page.)
The motor power supply should be shut off after the STOP command (CN4 14pin STOP) is turned ON.
Refer to “6.3 Details of parallel input / output signal and cable” for the STOP command
Warning
- Do not perform a return to origin position when the the power supply for the motor (M24V) is off. The
controller cannot recognize the correct origin if a return to origin instruction is made with the motor
drive power (M24V) disconnected.
- If the M24V is off during electric actuator operation, there will be an additional delay experienced
before it stops (the stop distance will be extended) due to inertia of the work piece or regenerated
energy. When the M24V is turned off, and the STOP command is turned ON (CN4 14pin STOP)
simultaneously the time to stop can be shortened.
- If the motor drive power is off during a vertical stop, the table may drop due to lock response.
- BK RLS is internally connected to the M24V inside the controller, so do not apply 24 VDC to the BK
RLS terminal when the M24V is off.
