inspecting and troubleshooting the product. Failure to do so may result in fire or

injury.

• When the driver’s protection function is triggered, first remove the cause and then

clear the protection function. Continuing the operation without determining the

cause of the problem may cause malfunction of the motor, leading to injury or

damage to equipment.

Installation

• Install the motor (gearhead) and driver in their enclosures in order to prevent

injury.

Connection

• Keep the driver’s input-power voltage within the specified range to avoid fire.

• Connect the cables securely according to the wiring example in order to prevent

fire.

• Do not forcibly bend, pull or pinch the cable. Doing so may 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.

2 Safety precautions

－5－

Operation

• Turn off the driver 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 use it in a vertical applications. When the driver protection function is

triggered, the motor will stop operating. The moving parts fall and may cause

injury or damage to equipment.

Repair, disassembly and modification

• Do not disassemble or modify the motor, gearhead or driver. This may cause

injury. Refer all such internal inspections and repairs to the branch or sales office

from which you purchased the product.

CAUTION

General

• Do not use the motor, gearhead and driver beyond their specifications, or injury or

damage to equipment may result.

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

The surfaces are hot and may cause a burn.

Transportation

• Do not hold the motor (gearhead) output shaft or motor cable. This may cause

injury.

Installation

• Keep the area around the motor and 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 motor and

driver that would obstruct ventilation.

• Provide a cover over the rotating parts (output shaft) of the motor (gearhead) to

prevent injury.

Operation

• Use a motor and driver only in the specified combination. An incorrect

combination may cause a fire.

• 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.

• Immediately when trouble has occurred, stop running and turn off the driver

power. Failure to do so may result in fire, electric shock or injury.

• To prevent bodily injury, do not touch the rotating parts (output shaft) of the motor

during operation.

• Release all driver input signals before turning on the power to the driver. Otherwise,

the motor may start suddenly and cause injury or damage to equipment.

 Noise measures

The electrical noise is of two types: One is a noise to invade into the driver from the

outside and cause the driver malfunction, and the other is a noise to emit from the

driver and cause peripheral equipments malfunction.

For the noise that is invaded from the outside, take measures to prevent the driver

malfunction. It is needed to take adequate measures because signal lines are very

likely to be affected by the noise.

For the noise that is emitted from the driver, take measures to suppress it.

Refer to p.15 for "Installing and wiring in compliance with EMC directive."

Measures against electrical noise

There are the following three methods mainly to take measures against the electrical

noise.

• Noise suppression

• When relays or electromagnetic switches are used together with the system, use

noise filters and CR circuits to suppress surges generated by them.

• Use an accessory cable when extending a wiring distance between the motor and

driver. This is effective in suppressing the electrical noise emitted from the motor.

• Cover the driver by a metal plate such as aluminum. This is effective in shielding

the electrical noise emitted from the driver.

• Prevention of noise propagation

• Place the power lines, such as the motor and power supply cables, keeping a

distance of 100 mm (3.94 in.) or more from the signal lines, and also do not

bundle them or wire them in parallel. If the power cables and signal cables have to

cross, cross them at a right angle.

• For more effective elimination of noise, use a shielded I/O signal cable or attach

ferrite cores if a non-shielded cable is used.

• Keep cables as short as possible without coiling and bundling extra lengths.

• To ground a shielded cable, use a metal

cable clamp that will maintain contact

with the entire circumference of the

cable. Ground the cable clamp near the

product.

Braided screen

cable

• When grounding PE terminals of multiple drivers to a grounding point, it becomes

more effective to block the electrical noise since impedance on the grounding

point is decreased. However, ground them so that a potential difference does not

occur among the grounding points.

• Suppression of effect by noise propagation

• Loop the noise propagated cable around a ferrite core. Doing so will prevent the

propagated noise invades into the driver or emits from the driver. The frequency

band in which an effect by the ferrite core can be seen is generally 1 MHz or more.

Check the frequency characteristics of the ferrite core used. To increase the effect

of noise attenuation by the ferrite core, loop the cable a lot.
