1. Safety precautions
When using the electromagnetic brake motor in a vertical drive application such as elevating
equipment, be sure to check the load condition suciently before operating. If a load exceeding the
rated torque is applied or the small torque limiting value is set, the load may fall. This may result in
injury or damage to equipment.
Only qualied and educated personnel should be allowed to perform installation, connection,
operation and inspection/troubleshooting of the product. Handling by unqualied and uneducated
personnel may result in re, electric shock, injury, or damage to equipment.
The motor is ClassⅠequipment. When installing the motor, ground the Protective Earth Terminal of
the motor. Failure to do so may result in electric shock.
Use a motor and driver only in the specied combination. An incorrect combination may cause re,
electric shock, or damage to equipment.
Always turn o the power before performing maintenance or inspection. Failure to do so may result
in electric shock.
Do not use the motor beyond the specications. Doing so may result in re, electric shock, injury, or
damage to equipment.
Do not touch the motor during operation or immediately after stopping. The surface of the motor is
hot and it may cause a skin burn(s).
Do not leave anything around the motor that would obstruct ventilation. Doing so may result in
damage to equipment.
Do not lift the motor by holding the output shaft or the cable. Doing so may result in injury.
Do not touch the motor output shaft (shaft end or pinion section) with bare hands. Doing so may
result in injury.
When assembling the motor with the gearhead, exercise caution not to pinch your ngers or other
parts of your body between the motor and gearhead. Injury may result.
When installing the motor in equipment, exercise caution not to pinch your ngers or other parts of
your body between the product and equipment. Injury may result.
Do not touch the rotating part (output shaft) during operation. Doing so may result in injury.
Securely install the motor on the mounting plate. Improper installation may cause the motor to come
loose and fall, resulting in injury or damage to equipment.
Provide a cover over the rotating part (output shaft). Failure to do so may result in injury.
Securely install a load on the output shaft. Failure to do so may result in injury.
Be sure to ground the motor and the driver to prevent damage from static electricity. Failure to do so
may result in re or damage to equipment.
The motor surface temperature may exceed 70 °C (158 °F) even under normal
operating conditions. If the operator is allowed to approach the operating motor,
attach a warning label on a conspicuous position as shown in the gure. Failure to do
so may result in a skin burn(s). Warning label

2. Precautions for use
This chapter covers restrictions and requirements the user should consider when using the product.
Be sure to match the motor output power to the driver output power.
Wiring
zConnecting a motor and a driver (Connector type)
To connect a motor and a driver, always use the dedicated connection cable (sold separately).
An electromagnetic brake motor requires a dedicated connection cable (sold separately) that is labeled for
electromagnetic brake motor.
Limit the number of times so that the connection/disconnection between the connection cable and the motor
or driver will not exceed 100 times.
zConnecting a motor and a connector (Connector type)
Do not apply a strong force to the locking lever of the connector for motor connection.
Applying a strong force to the locking lever may cause damage.
zConnecting a motor and a driver
When extending the wiring distance between the motor and the driver, use the connection cable (for
extension), which is sold separately.
The length of the cable that can be connected varies depending on the driver used. Refer to the operating
manual of the driver.
Installation environments
zGrease measures
On rare occasions, grease may ooze out from the gearhead. If there is concern over possible environmental
contamination resulting from the leakage of grease, check for grease stains during regular inspections.
Alternatively, install an oil pan or other device to prevent damage resulting from contamination. Grease leakage
may lead to problems in the user’s equipment or products.
zWhen using in low temperature environment
When the ambient temperature is low, the load torque may increase due to the oil seal or the viscosity of the
grease used in the gearhead, and the output torque may decrease or the overload alarm may be generated.
However, as time passes, the oil seal or grease is warmed up, and the motor can be operated without generating
the overload alarm.
zApply grease to the hollow output shaft of a hollow shaft at gearhead.
When using a hollow shaft at gearhead, apply grease (molybdenum disulde grease, etc.) on the surface of the
load shaft and inner walls of the hollow output shaft to prevent seizure.
Insulation resistance measurement and dielectric strength test
zDo not conduct the insulation resistance measurement or the dielectric strength test
with the motor and driver connected.
Conducting the insulation resistance measurement or dielectric strength test with the motor and driver
connected may result in damage to the product.
Operations
zUse an electromagnetic brake motor in a vertical drive application such as elevating
equipment.
When the motor is used in a vertical drive application such as elevating equipment (lifting and lowering device),
use an electromagnetic brake motor so that the load can be held in position.
Note If a power failure occurs or the protective function of the driver is activated in a state where a
motor without an electromagnetic brake is used, the moving part may fall when the motor stops.
This may cause injury or damage to equipment.
zRotation direction of the gearhead output shaft
Parallel shaft gearhead
The rotation direction of the gearhead output shaft may dier from that of the motor output shaft depending
on the gear ratio of the gearhead.
Gear ratio Rotation direction of the gearhead output shaft
5, 10, 15, 20, 200 Same direction as the motor output shaft
30, 50, 100* Opposite direction to the motor output shaft
* Same direction as the motor output shaft when the gear ratio is 100 for the 200 W and 300 W motors
Hollow shaft at gearhead
The rotation directions of the gearhead output shaft relative to the motor output shaft are as shown in the
gures below.
Check the operating manual of the driver for the rotation direction of the motor output shaft relative to the
operation input signals of the driver.
Motor output shaft Gearhead output shaft
Front Rear
zSliding noise of electromagnetic brake
Sliding noise of the brake disk for the electromagnetic brake motor may be generated during operation.
It is no functional problem.
