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.

Caution

Warning

Note The items under this heading contain important

handling instructions that the user should observe to

ensure safe use of the product.

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.

• When pulses are input, the motor rotates one step as the pulses

start (pulse fall).

• The voltage of the pulse signal is ON: +4.5 to +5.5V, OFF: 0 to

+0.7V. Input-pulse signals should have a pulse width exceeding

1µsec, pulse rise/fall below 1µsec, and a pulse duty of less than

50%.

Driving motor current

The D2D2043-S can drive motors with a rated current of up to

4.38A/phase. However, we recommend you follow the drive

conditions below in view of the rating of internal heat generation

(which affects product life).

(Running current)2 × X + (Standstill current)2 × (1

X) < 7.5

X: Motor’s operating duty relative to operation time

Example) If the motor is used at an operating duty of 100% or

standstill current of 100%, the running current will be

2.12A/phase or less.
