failure or malfunction. Failure to do so may result in injury.
yWhen an alarm is generated in the driver (any of the driver's protective functions
is triggered), take measures to hold the moving part in a specic position since the
actuator stops and loses its holding torque. Failure to do so may result in injury or
damage to equipment.
yWhen having replaced the driver, set the resolution, the traveling direction or others
before operating. If the actuator is operated without setting the resolution or the
traveling direction, the output table may move to unexpected directions or run at
unexpected speeds, leading to injury or mechanical damage.
Installation
yInstall the actuator inside an enclosure. Failure to do so may result in injury.
yWhen installing the actuator, install it inside an enclosure so that it is out of the direct
reach of users. Be sure to ground if users can touch it. Failure to do so may result in
electric shock.
Connection
yDo not forcibly bend, pull, or pinch the lead wire or cable. Doing so may result in re.
Repair, disassembly, and modication
yDo not disassemble or modify the actuator. Doing so may result in injury or damage to
equipment.
General
yDo not use the actuator beyond its specications. Doing so may result in injury or
damage to equipment.
yKeep your ngers and objects out of the openings in the actuator. Failure to do so may
result in re, electric shock or injury.

Precautions for use
This section covers restrictions and requirements the user should consider when using
the product.
•When conducting the insulation resistance measurement or the
dielectric strength test, be sure to separate the connection between the
actuator and the driver.
Conducting the insulation resistance measurement or dielectric strength test with the
actuator and the driver connected may result in damage to the product.
•Do not apply an axial load and moment load in excess of the specied
permissible limit
Be sure to operate the actuator within the specied permissible limit of axial load and
moment load. Continuing to operate the actuator under a axial load or moment load
exceeding the permissible value may cause malfunction or shorter service life of the
actuator.
•Use the actuator in conditions where the motor surface temperature
does not exceed 100 °C (212 °F).
If the motor surface temperature exceeds 100 °C (212 °F) due to the operating conditions
(ambient temperature, operating speed, operating duty, etc.), the motor windings may
burn out or the lifetime of the bearings (ball bearings) may be reduced.
•Rotation direction of output table
The rotation direction of the output table varies depending on the setting of the travel
amount or the input method of the pulse signal.

Operation by pulse signal
y2-pulse input mode
Input the pulse signal to the CCW input
y1-pulse input mode
Input the pulse signal to the PLS input while the
DIR input is OFF.
•Holding torque at standstill
The motor holding torque is reduced by the current cutback function of the driver
at actuator standstill. When selecting a actuator, check the holding torque at motor
standstill in the specications on the catalog.
zNotes when the connection cable is used
Note the following points when our cable is used.
•When inserting the connector
Hold the connector main body, and insert it in straight securely. Inserting the connector
in an inclined state may result in damage to connector or a connection failure.
•When pulling out the connector
Hold both ends of the connector main body, and pull out it straight. Pulling out the
connector with holding the lead wire may result in damage to the connector.
Secure the lead wires at the connection part of the connector to prevent the
connector or terminals from receiving stress due to bending or self-weight of
lead wires. Also, do not excessively bend the lead wires near the connection
part of the connector. Applying stress on the lead wires may cause poor
contact or disconnection, leading to malfunction or heat generation.
