The assembly, operation and maintenance of machines or equipment including our products must be performed
by an operator who is appropriately trained and experienced.
3. Do not service or attempt to remove product and machinery/equipment until safety is confirmed.
1.The inspection and maintenance of machinery/equipment should only be performed after measures to
prevent falling or runaway of the driven objects have been confirmed.
2.When the product is to be removed, confirm that the safety measures as mentioned above are implemented
and the power from any appropriate source is cut, and read and understand the specific product precautions
of all relevant products carefully.
3.Before machinery/equipment is restarted, take measures to prevent unexpected operation and malfunction
4. Contact SMC beforehand and take special consideration of safety measures if the product is to be
used in any of the following conditions.
1.Conditions and environments outside of the given specifications, or use outdoors or in a place exposed to
direct sunlight.
2.Installation on equipment in conjunction with atomic energy, railways, air navigation, space, shipping,
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 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.
Keep this operation manual accessible for reference.
