2. Outlines of Product
2.1 Features
Features of the controller.

Actuator control
Servo control enables the positioning and the operation with a specified thrust of
the actuator.

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.

Operation with specified thrust
The holding force and pushing force of the actuator can be controlled in three steps.

Separated power supply input
Power supply input is separated into the motor power supply and control power supply.
Even if the power supply for the motor is turned off, the information of the encoder position is
not lost while the control power supply is on, and parallel I/O control is available.

Automatic sequence function of the returning to origin position
Returning to origin position is available through I/O signal combination.

Alarm detection
Abnormal conditions are self-detected. Alarms are displayed by LED on the controller and
abnormal conditions are output to the outside by the parallel I/O terminal.

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.

Caution
(1) A dedicated Ground connection must be used. Use a D-class ground connection
(ground with a resistance of less than 100Ω).
(2) The cross sectional area of the grounding cable shall be 2mm2or more.
Grounding location shall be in the vicinity of the controller. Keep the grounding cable short.
(3) The controller case mounting part is connected to 0V of the power supply.
(3) Location for mounting
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 as shown. Leave a minimum of 30 mm of clearance at the top of the
controller or 60 mm below the controller so that the cables can be connected and disconnected.
Keep 60mm or more between the front of the controller and the cover (lid) so that buttons and switches can be
operated.
Keep enough space 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.
Caution
When there are dents, bumps or warping on the mounting surface of the controller, excessive
force can be applied to the case, which can cause failure. Mount on a flat surface.

(2) Wiring of forced unlocking switch
When manual unlock is required for adjustment or reset of the actuator with lock, please install a switch. *
The switch (24V DC, contact capacity: 0.5A or more) needs to be prepared by the user.
One side of the switch should be connected to the positive side of the controller input power supply 24V DC,
and the other side should be connected to the BK RLS terminal of the power supply plug. When the switch
is closed, the controller/motor is forcibly unlocked.
Caution
For the actuator without lock, please do not connect the BK RLS terminal.
The only case where 24V DC can be applied to the BK RLS terminal is as described below, 24V DC
should not be applied in other cases.
- 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 24VDC 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 Parallel input signals for the STOP command.
Warning
-Do not perform return to origin when the the motor drive power (M24V) is disconnected. The
controller cannot recognize the correct origin point if a return to origin instruction is made with the
motor drive power (M24V) disconnected.
- If the M24V is shut off during actuator operation, there will be an additional delay experienced
before it stops (the stop distance will be extended) due to inertia of work pieces or regenerated
energy. When the M24V is tutned off, and the the STOP command is turned ON（CN4 14pin
STOP）simultaneously the the time to stop can be shortened.
- If the motor drive power is shut off during vertical stop, the table may drop due to brake response.
- BK RLS is internally connected to the M24V in the controller, so please do not apply 24V DC to the
BK RLS terminal when the M24V is shut off.
