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).
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.
Specified force operation
Control the pushing force (or the pressing force) of the electric actuator.
Power supply separation input
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.
Automatic sequence function of the return to origin position
Return to origin position is available through I/O signal combination.
Alarm detection function
Automatically detect the abnormal conditions and output the appropriate alarm signal via the
serial interface and parallel I/O.
14 points positioning / pushing is available
Through the combination of parallel I/O inputs, 14 points (position number 1 to 14(E)) of
positioning / pushing are available. The speed and acceleration of the positioning can be set by
the switch for each operating direction.
Data input method
Parameter settings, test runs, and alarm resets can be performed by the controller.
Caution
When the device is set up or failure occurs, please refer to the operation manual of the actuator as well
as this operation manual.
Keep this operation manual accessible so it can be referred to when necessary.

ALM
Red LED is ON
Alarm is generated
Under normal conditions, the LED [PWR] on the front of the controller changes from a flashing green
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 lights up red, it indicates an alarm.
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 “11. Alarm Detection”.
(5) Data (Operation pattern) setting
Set the stop position, speed and acceleration per operating direction with the buttons and switches on
the controller.
Operations other than position setting, Jog / inching can be performed after returning to origin position.
Refer to “7. Setting method”for the details of settings.
(6) Test run
Test runs can be performed using the buttons on the controller or by using I/O signals.

(Installation with two M4 screws)
Grounding cable Grounding cable Grounding cable
(2) Grounding cable 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.
Controller attaching hole (Installation position of grounding cable) and SG (Signal ground) are
connected in the controller.
Please do not ground the controller when using it in the plus earth environment.

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 40oC
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.
