Safety precautions

•Do not use the cylinder in explosive or corrosive environments, in the

presence of ammable gases, locations subjected to splashing water, or near

combustibles. Doing so may result in re or injury.

•Do not transport, install, connect or inspect the cylinder while the power is

supplied. Doing so may result in electric shock.

•Do not forcibly bend, pull or pinch the cable. Doing so may result in re.

•Do not disassemble or modify the cylinder. Doing so may result in injury or

damage to equipment.

•Never use the cylinder in a medical device used in connection with the

maintenance or management of human life or health, or in a transportation

system whose purpose is to move or carry people.

•Be sure to provide a safety cage conforming to EN ISO 13857 to prevent

persons from entering the moving range of the cylinder while power

is supplied to the cylinder. Turn o the main power to the driver before

performing adjustment or inspection in which the moving part is moved

manually. Failure to do so may result in injury.

•Do not hit the ball screw with the mechanical stopper in operations other

than push-motion operation. Doing so may result in injury or damage to

equipment.

•Assign qualied personnel to the task of installing, wiring, operating/

controlling, inspecting and troubleshooting the cylinder. Failure to do so

may result in re, injury or damage to equipment.

•When setting the data, do so outside the safety cage. Failure to do so may

result in injury.

•Take measures to keep the moving part in position if the cylinder is used in

vertical operations such as elevating equipment. Failure to do so may result

in injury or damage to equipment.

•When 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 cylinder stops and loses its holding torque. Failure to do so

may result in injury or damage to equipment.

•Install the cylinder inside an enclosure. Failure to do so may result in 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 injury.

•After replacing the driver, set the resolution, traveling direction or other

parameters before operating the cylinder. If the cylinder is operated without

setting parameters, the ball screw may move to unexpected directions or run

at unexpected speeds, causing injury or damage to equipment.

Safety precautions

•Do not use the cylinder beyond its specications. Doing so may result in

injury or damage to equipment.

•Keep your ngers and objects out of the openings in the cylinder. Failure to

do so may result in re or injury.

•Do not touch the cylinder during operation or immediately after stopping.

Doing so may result in a skin burn(s).

•Do not carry the cylinder by holding the moving part or cable. Doing so may

cause injury.

•Keep the area around the cylinder free of combustible materials. Failure to

do so may result in re or a skin burn(s).

•Do not leave anything around the cylinder that would obstruct ventilation.

Doing so may result in damage to equipment.

•Do not touch the moving part during operation. Doing so may result in

injury.

•Do not touch the terminals while conducting the insulation resistance

measurement or dielectric strength test. Doing so may result in electric

shock.

•While the cylinder is operated, do not make the cable contact with the

moving part. Doing so may result in disconnection in the cable, leading to

damage.

•Use the cylinder and driver only in the specied combination. Failure to do

so may result in re.

•Wear a helmet, safety shoes, gloves or other protective gear when

transporting or installing the cylinder. Failure to do so may result in injury.

•The motor surface temperature may exceed 70 °C (158 °F)

even under normal operating conditions. If the operator is

allowed to approach the cylinder in operation, ax a warning

label shown in the gure on a conspicuous position. Failure to

do so may result in a skin burn(s).

Precautions for use

3 Precautions for use

This chapter covers restrictions and requirements the user should consider when using the

product.

General

zBe sure to use our cable to connect the cylinder and driver.

Check on the Oriental Motor Website for the model name of cables.

zDo not detach the table or loosen the screws.

If the table is detached or the screws secured the table is loosened, the installation accuracy

of the ball screw is deteriorated, resulting in malfunction or shorter service life of the cylinder.

Also, the home position set in the encoder (ABZO sensor) at the time of shipment may be

deviated, and this may cause unexpected movements, leading to damage to equipment.

zDo not install a guide for load transportation additionally on the customer side.

Misalignment of guides may cause damage to equipment.

zWhen conducting the insulation resistance measurement or the dielectric

strength test, be sure to separate the connection between the cylinder and the

driver.

Conducting the insulation resistance measurement or dielectric strength test with the cylinder

and driver connected may result in damage to the product.

zDo not make an impact on the cylinder.

Do not drop the cylinder. Also, do not hit or strike the cylinder. Making an impact on the

cylinder may cause the positioning accuracy to decrease, the motor to damage, or the lifetime

to reduce.

zMake sure not to hit or apply a strong impact on the encoder (ABZO sensor).

•Making a strong impact on an encoder (ABZO sensor) may cause the motor malfunction or

damage to the encoder (ABZO sensor).

•When transporting the cylinder or installing a load, handle the cylinder carefully not to

make a strong impact on the moving part.

•The warning label shown in the gure is indicated on

the motor.

Warning label

zMeshing noise of mechanical sensor

A gear type mechanical sensor is built into the encoder (ABZO sensor). Although the meshing

noise of gears may generate, it is not malfunction.

Precautions for use

zDo not move the encoder (ABZO sensor) toward a strong magnetic eld.

A magnetic sensor is built into the encoder (ABZO sensor). If the cylinder is installed close to

equipment which generates a strong magnetic eld, the encoder (ABZO sensor) may break

or malfunction. Make sure the environment at transportation and storage as well as the

installation location in use. Keep the magnetic ux density on the surface of the encoder (ABZO

sensor) so as not to exceed the values in the table.

Model Magnetic ux density

When transporting and storing When operating

DR28 5 mT 2 mT *

* When the magnetic ux density is exceeding 1 mT and 2 mT or less, use in an environment

where the operating ambient temperature is exceeding 20 °C (68 °F) and 40 °C (104 °F) or

less.

Temperature

zUse the cylinder in a condition where the motor surface temperature does not

exceed 80 °C (176 °F).

The motor surface temperature may exceed 80 °C (176 °F) under certain conditions (ambient

temperature, operating speed, duty cycle, etc.). In order to protect the encoder (ABZO sensor),

use the motor in a condition where the motor surface temperature does not exceed 80 °C

(176 °F).

If the encoder (ABZO sensor) temperature reaches the upper limit, the motor overheat

protection alarm will generate.

zOperate the cylinder in the range of the operating ambient temperature.

If the cylinder is used outside of the operating ambient temperature, it may not operate

properly.

Operation

zKeep 20 m (65.6 ft.) or less for the wiring distance between the cylinder and

driver.

To extend more than 20 m (65.6 ft.) may cause the thrust to reduce.

zHolding torque at standstill

The holding force at standstill for the cylinder is a value when the current cutback function

(stop current 50%) is enabled. Note the holding force is reduced in the current cutback state.

In addition, turning o the power supply causes the holding force of the cylinder to lose.

Make sure a load does not fall.

zDo not perform push-motion operation at the speed exceeding the maximum

push speed or the maximum push-motion return-to-home speed.

The mechanical impact may cause damage to the cylinder. If the ball screw was pressed at

high speed, take measures by referring to "8 Troubleshooting" on p.23.

Precautions for use

zDo not perform push-motion operation with the cylinder of ball screw lead

1 mm.

The TLC output may be turned ON before push-motion operation is complete. (Push-motion

return-to-home operation can be performed.)

Inspection

zGrease

Grease on the ball screw or linear guide may darken during the initial operation (one to three

weeks). Refer to p.20, and wipe o the dirty grease to apply new grease.

Notes when the connection cable is used

Note the following points when our cable is used.

zWhen 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 terminals or a connection failure.

zWhen unplugging the connector

Pull out the connector in straight while releasing the lock part of the connector. Pulling out

the connector with holding the lead wire may result in damage to the connector.

zBending radius of cable

Use the cable in a state where the bending radius of

the cable is more than six times of the cable diameter.

Do not bend the lead wires part or x it with a clamp.

Doing so may cause damage to the connector.

More than 6 times

of cable diameter

Do not bend the

lead wires part

zHow to x the cable

Fix the cable near the connectors at two places as shown in the gure or x it with a wide

clamp to take measures to prevent stress from being applied to the connectors.

In the case of a exible cable,

this area is a movable range.
