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 supply 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.

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

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

injury.

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

Otherwise, the motor may start suddenly and cause injury or damage to

equipment.

2 Safety precautions

−6−

• Before moving the motor directly with the hands (as in the case of manual

positioning), confirm that the driver operation input is “OFF” to prevent injury.

• Do not perform the motor’s starting and stopping operations by turning the power

supply on and off. Perform them by inputting START/STOP and RUN/BRAKE.

This may cause injury or damage to the equipment.

• The motor’s surface temperature may exceed 70 °C, even under

normal operating conditions. If a motor is accessible during

operation, post a warning label shown in the figure in a

industrial waste.

3 Precautions for use

−7−

3 Precautions for use

This chapter explains the restrictions and other items you should take heed of when

using the BLH series.

• Do not perform gravitational load operation

With the BLH series, any operation in which the motor output shaft is turned from

the load side (gravitational load operation) will disable the motor speed control. In

addition, a gravitational load operation will cause the driver’s primary inverter

voltage to exceed the allowable value, thereby triggering a protection function and

causing the motor to stop spontaneously. If this happens, there is a possibility that

the load will drop.

• Grease measures

On rare occasions a small amount of grease may leak from the gearhead. If leaked

grease is feared to contaminate the surrounding environment, check for grease

leakage during regular inspections or provide an oil pan or other device to prevent

damage resulting from contamination. Leaking oil is a cause of malfunction in your

equipment or product.

• Apply grease on the output shaft of the hollow shaft flat gearhead

If you are using a gearhead, apply grease (molybdenum disulfide grease, etc.) on the

surface of the load shaft and inner walls of the hollow output shaft to prevent

seizure.

• Conduct the insulation resistance measurement or withstand voltage

test separately on the motor and the driver

Conducting the insulation resistance measurement or withstand voltage test with the

motor and driver connected may result in injury or damage to equipment.

• Noise elimination measures

Provide the following noise elimination measures to prevent a motor or driver

malfunction caused by external noise.

Wiring the motor

To extend the wiring between the motor and driver, use the accessory extension

cable (sold separately).

Wiring the I/O signals cable

• Minimize the wiring length of the I/O signals cable.

• Provide a minimum clearance of 100 mm (4 in.) between the I/O signals cable and

any inductive load such as an electromagnetic relay or any power line (power

supply, motor, etc.). Do not place the I/O signals cable and a power line in the

same duct or pipe or bundle them together.

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

ferrite cores if a non-shielded cable is used.
