●
Please read it thoroughly to ensure safe operation.
●
Always keep the manual where it is readily available.

Introduction
The precautions described below are intended to prevent
danger or injury to the user and other personnel through
safe, correct use of the product. Use the product only after
carefully reading and fully understanding these instructions.

Handling the product without observing the instructions
that accompany a “Warning” symbol may result in serious
injury or death.
●
Do not use the product in explosive or corrosive envi-
ronments, in the presence of flammable gases, loca-
tions subjected to splashing water, or near com-
bustibles. Doing so may result in fire or injury.
●
Assign qualified personnel the task of installing, wiring,
operating/controlling, inspecting and troubleshooting
the product. Failure to do so may result in fire or injury.
●
Provide a means to hold the moving parts in place for ap-
plications involving vertical travel. The motor loses
holding torque when the power is shut off, allowing the
moving parts to fall and possibly causing injury or dam-
age to equipment.
●
Install the motor in an enclosure in order to prevent in-
jury.
●
Keep the input-power voltage within the specified range
to avoid fire.
●
Connect the cables securely according to the wiring di-
agram in order to prevent fire.
●
Do not forcibly bend, pull or pinch the cable. Doing so
may fire.
●
For the power supply use a DC power supply with rein-
forced insulation on its primary and secondary sides.
Failure to do so may result in electric shock.
●
Turn off the power in the event of a power failure, or the
motor will suddenly start when the power is restored
and may cause injury or damage to equipment.
●
Do not disassemble or modify the motor. This may
cause injury. Refer all such internal inspections and re-
pairs to the branch or sales office from which you pur-
chased the product.
How to install the motor
Install the motor onto an appropriate flat metal plate having
excellent vibration resistance and heat conductivity. When
installing the motor, secure it with four bolts (not supplied)
through the four mounting holes (or tapped holes) provided.
Leave no gap between the motor and plate.

Handling the product without observing the instructions
that accompany a “Caution”symbol may result in injury or
property damage.
●
Do not use the motor beyond its specifications, or in-
jury or damage to equipment may result.
●
Do not touch the motor during operation or immediate-
ly after stopping. The surface is hot and may cause a
burn.
●
Do not hold the motor output shaft or motor cable. This
may cause injury.
●
Provide an emergency-stop device or emergency-stop
circuit external to the equipment so that the entire
equipment will operate safely in the event of a system
failure or malfunction. Failure to do so may result in in-
jury.
●
To prevent bodily injury, do not touch the rotating parts
(output shaft) of the motor during operation.
●
Immediately when trouble has occurred, stop running
and turn off the power. Failure to do so may result in fire,
electric shock or injury.
●
Conduct the insulation resistance measurement or with-
stand voltage test separately on the motor and the dri-
ver. Failure to do so may result in equipment damage.
●
To dispose of the motor, disassemble it into parts and
components as much as possible and dispose of indi-
vidual parts/components as industrial waste.
To verify that the unit you’ve purchased is the correct one,
check the model number shown on the identification plate.
Report any incorrect or damaged item to the branch or sales
office from which you purchased the product.
Checking the product
Before using the motor
Only qualified personnel should work with the product.
Use the product correctly after thoroughly reading the section
“Safety precautions”.
The product described in this manual has been designed
and manufactured for use in general industrial machinery,
and must not be used for any other purpose. For the power
supply use a DC power supply with reinforced insulation on
its primary and secondary sides. Oriental Motor Co., Ltd. is
not responsible for any damage caused through failure to
observe this warning.
●
Tapped hole type
The square box in the motor type will contain a number representing
the motor length. (No.4-40UNC): USA model type
Permissible overhung load
and permissible thrust load
The overhung load on the motor’s output shaft or gear out-
put shaft must be kept within the permissible values listed
below. The thrust load must not exceed the motor’s mass.
It is recommended that periodic inspections be conducted
for the items listed below after each operation of the motor.
If an abnormal condition is noted, discontinue any use and
contact your nearest office.
●
Check for any unusual noises in the motor’s bearings (ball
bearings) or other moving parts.
●
Are there any scratches, signs of stress or loose driver
connections in the motor cable?
●
Are the motor’s output shaft and load shaft out of align-
ment?
Inspection
●
Unauthorized reproduction or copying of all or part of
this Operating Manual is prohibited.
●
Characteristics, specifications and dimensions are sub-
ject to change without notice.
●
