2. Product Outline

2.1 Product features

The followings are the main functions of this driver:



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).



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 driver.



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.



Specified force operation
Control the pushing force (or the pressing force) of the electric actuator.

Caution

The operation with specified thrust is available for driver version 1.60 or more.

Please refer to the “3.2 Parts description (page 13)” for the confirm method of the driver version.

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.

Caution

For driver input power supply (24 VDC) use a power supply with a capacity not less than the

“momentary maximum power” of the electric actuator spedfications. Do not use “inrush current
restraining type” power supply.

(2) Wiring of the stop switch

By connecting 24V to EMG, motor becomes operable. Without connect the 24V to EMG, motor does not

move. Stop switch must be installed by the user to stop the electric actuator in abnormal situations.
Please refer to “5.4 Stop circuits” for examples of how to wire stop switches.

Caution

The Servo is not ON unless a voltage of 24 VDC is applied to the EMG terminal.

(3) 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 plug Lock release switch

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.

After the wiring of the power supply plug is completed, connect it to the CN1 connector of the driver.
Please refer to “5.3 Wiring of power supply plug” for how to wire the power supply plug.

Warning

(1) Relay contacts should be made between the 24 VDC driver power supply and the M24V and

EMG terminal of the power supply plug. The electric actuator may make unexpected movement.

(2) When at the same time to OFF EMG and the power, For the inertia of the load, you might have to

take time until the motor stops.

(3) Do not perform return to origin (SETUP input ON) when motor drive power (M24V) is

disconnected. The driver cannot recognize the correct origin point if a return to origin instruction

is made with the motor drive power (M24V) disconnected.

(4) If the electric actuator with lock is used vertically, delay in response of the brake may occur when

shutting off the motor power supply (M24V), and the moving part of the electric actuator may

drop due to the weight of the electric actuator itself.

(5) Do not energize to the BK RLS terminal when there is a necessity to shut down the motor drive

power (M24V) externally.

Because the BK RLS terminal is connected with M24V in the driver, the electric actuator may do

unexpected operation. Please turn off the EMG terminal when energizing to the BK RLS terminal

at motor drive power is OFF.
