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.

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.

(8) Noise filter set
ＬＥＣ－ＮＦＡ
Noise filter set
Assembly procedure:
1) Mount a noise filter around the single wires of the actuator cable close to the driver connectors.
Next, fasten a cable tie to the shrink sleeve as shown (refer to A1).
2) Mount a noise filter to the motor cable, and fasten with a cable tie at both ends.
CN2 and CN3 connectors Actuator cable
Single wires Cable tie
Driver Noise filter Shrink sleeve
Motor cable
Caution
When installing a noise filter on the actuator cable, bundle all of the single wires together and then
house them inside the noise filter case. When locking the noise filter, make sure not to damage the
wires.
Attach the noise filter at the root of the cable immediately next to the connector.
When unplugging the actuator cable connectors CN2 and CN3 from the driver, remove the cable tie
and move the noise filter towards the shrink sleeve. After re-mounting, return the noise filter to its
original position and re-fasten the cable tie.

(2) Installation
Please refer to the “3.4 How to install”
(3) Wiring and connection
Connect cables, etc. to the connector (CN1 to CN5) of the driver.
Please refer to the “5 External Wiring Diagram” for the wiring of the connectors.
(4) Power ON alarm (error)
Ensure the stop is not activated and then supply 24VDC power.

Problems
Driver
If the LED [PWR] lights in green, the driver is in the normal condition.
However, if the LED [ALM] lights in red, the driver is in the alarm (error) condition.
Caution
In case of alarm (error) condition:
Connect a PC or the teaching box to the CN4 serial I/O connector and check the details of the alarm.
Then, remove the cause of the error referring to the “12. Alarm Detection”
Please refer to the manuals of the controller setting software or the teaching box for details of the
alarms.

(5) Operation pattern setting
Setup the operation pattern (step data, basic parameter and return to origin parameters) by using a
Controller setting kit or the teaching box. Specifically, be sure to configure the parameter"option set
1” from the basic parameters section. Refer to “7. Setting Data Entry (page 31)” for details.
● Controller set up kit ● Teaching box
Please refer to the manuals of the controller setting software or the teaching box for how to setup the
operation pattern
[1] Counts of input pulses
The pulse number input from the positioning unit is
displayed. However, please take care that under the
situation that the driver doesn't count the pulse (The
SVRE power output: turning off, the return to origin
inside, and
CLR input: turn on, Test in operation by Controller
setting kit /teaching box), this value is changed.
[2] Value converted into pulse
The values about the speed and the target position, current position converted into the pulse
number are displayed. Conversion formula is shown in below.
Position [Pulse]
= Position [mm] / Actuator lead [mm/rotation] x 800 [Pulse/rotation] x electronic gear
(denominator) / electronic gear (numerator)
Speed [Pulse/sec]
= Speed [mm/s] / Actuator lead [mm/rotation] x 800 [Pulse/rotation] x electronic gear
(denominator) / electronic gear (numerator)
Please refer to “7.2 Basic parameter” for electronic gear (denominator, numerator).
(6) Trial run (Electric actuator adjustment)
After confirming that an unexpected operation can be stopped externally, check the operation by inputting
the pulse signal from the positioning unit.
