Introduction
Before using the driver
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.
OPERATING MANUAL
Microstep Driver for 2-Phase
Stepping Motor
Thank you for purchasing an Oriental Motor product.
This Operating Manual describes product handling procedures and
safety precautions.
• Please read it thoroughly to ensure safe operation.
• Always keep the manual where it is readily available.
Caution
• Do not use the driver beyond its specification, or injury or damage
to equipment may result.
• Do not touch the driver’s heat sink during operation or immediately
after stopping. The surface is hot and may cause a burn.
• Keep the area around the driver free of combustible materials in
order to prevent fire or a burn.
• To prevent the risk of damage to equipment, leave nothing around
the driver that would obstruct ventilation.
• Use a motor and driver only in the specified combination. An
incorrect combination may cause a fire.
• To avoid injury, remain alert during operation so that the motor can
be stopped immediately in an emergency.
• Before supplying power to the driver, turn all input signals to the
driver to “OFF”. Otherwise, the motor may start suddenly and
cause injury or damage to equipment.
• When an abnormality is noted, stop the operation immediately, or
fire or injury may occur.
• When disposing of the driver, treat it as industrial waste.
Precaution
Checking the product
Upon opening the package, verify that the items listed below are
included.
Report any missing or damaged items to the branch or sales office
from which you purchased the product.
• Driver 1 unit
• Operating manual 1 copy
Overview of the product
This is a 2-phase microstep driver for use with a 2-phase stepping
motors. The use of a microstep drive, which electrically divides the
basic step angle of a 2-phase motor, offers reduced vibration and
noise in the low-speed range compared with the levels in full-step
mode.
• Do not turn the C.OFF (All windings off) input to “ON” while the
motor is operating. The motor will stop and lose its holding ability,
which may result in injury or damage to the equipment.
• Do not disassemble or modify the driver. This may cause injury.
Refer all such internal inspections and repairs to the branch or sales
office from which you purchased the product.

Safety precautions
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.
Warning
• Do not use the product in explosive or corrosive environments, in
the presence of flammable gases, locations subjected to splashing
water, or near combustibles.
• 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.
• Install the driver in an enclosure in order to prevent injury.
• Keep the driver’s input-power voltage within the specified range to
avoid fire.
• For the driver’s power supply, use a DC power supply with
reinforced insulation on its primary and secondary sides. Failure to
do so may result in electric shock.
• Connect the cables securely according to the wiring diagram in
order to prevent fire.
• Do not forcibly bend, pull or pinch the power cable or motor lead
wire. Doing so may result in fire.
• Turn off the driver power in the event of a power failure, or the motor
may suddenly start when the power is restored and may cause
injury or damage to equipment.
• If this product is used in an vertical application, be sure to provide a
measure for the position retention of moving parts. The motor loses
its holding torque when the power is turned off. Failure to provide
such a measure may cause the moving parts to fall, resulting in
injury or damage to the equipment.
Handling the product without observing the
instructions that accompany a “Warning” symbol may
result in serious injury or death.
Handling the product without observing the
instructions that accompany a “Caution” symbol may
result in injury or property damage.

Driver
Connection
Power source connection
The power-supply input voltage is 24VDC
-
40VDC±10%. Use a power source that can supply the following current capacity.
Applicable lead wire diameter: AWG26 ~ 16 (0.14 ~ 1.5mm2)
Note
• Make the input-signal voltage 5VDC minimum and 24VDC maximum. When
the input-signal voltage is 5VDC, external resistor R1 is not necessary. If the
input-signal voltage is greater than 5VDC, connect external resistor R1, to
restrict the input current as follows:
PLS: 7mA ~ 14mA
DIR./C.OFF: 10mA ~ 14mA
• Use an output-signal voltage of 5VDC minimum and 30VDC maximum, and
use output-signal current of 5mA max. If the output-signal current is greater
than 5mA, connect external resistor R2, to restrict the current to no more than
5mA.
