1. Safety precautions
When the overheat protection device (thermal protector) of the electromagnetic brake motor is
activated, the electromagnetic brake does not hold the motor shaft (a load). Provide safety measures
separately. This may result in injury or damage to equipment.
The motor is Class
Ⅰ
equipment. Install the motor so that it is out of the direct reach of users, or ground
if users can touch it. Failure to do so may result in electric shock.
Always keep the power supply voltage within the specied range. Failure to do so may result in re or
electric shock.
Perform connections securely according to the connection diagram. Failure to do so may result in re
or electric shock.
Insulate the connection terminals of the included capacitor. Failure to do so may result in electric
shock.
Turn o the power in the event of a power failure. Otherwise, the motor may suddenly start when the
power is restored, causing injury or damage to equipment.
Do not use the motor beyond the specications. Doing so may result in re, electric shock, injury, or
damage to equipment.
Do not lift up the motor by holding the output shaft, the lead wire, 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.
Keep the area around the motor free of combustible materials. Failure to do so may result in re or 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 touch the motor while operating or immediately after stopping. The surface of the motor is
hot and it may cause a skin burn(s).
Do not touch the rotating part (output shaft, cooling fan) while operating the motor. Doing so may
result in injury.
Provide a cover over the rotating part (output shaft). Failure to do so may result in injury.
When an abnormality is generated, turn o the power immediately. Failure to do so may result in re,
electric shock, or injury.
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

zConnection diagram
Insulate all the wire connections, such as the connection between the motor and the power supply and that
between the motor and the capacitor. Use the Protective Earth Terminal to ground the motor.
For safety, install a breaker or a fuse in the power supply line.
The motor rotates in the clockwise direction if the switch (SW2) is connected to the CW side, and it rotates in the
counterclockwise direction if connected to the CCW side.
Use lead wires for power supply equal to or thicker than the lead wire size of AWG 20 (0.5 mm2).
Note In the case of electromagnetic brake motors of 60 W and 90 W types, do not damage the inner
lead wire when stripping the outer sheath of the cable.

zOperation/Stop
Refer to“5. Operation”on p.22 when operating.
SW1 is used for“Operation-Stop”of the motor. Turning SW1 ON releases the electromagnetic brake to rotate the
motor. Turning SW1 OFF actuates the electromagnetic brake to stop the motor. A load may fall if the product is
used in vertical drive. Operate it after thoroughly checking the load condition.
•The electromagnetic brake is a friction type. Friction noise may occur when the electromagnetic
brake is actuated, but this is not a problem.
•If the electromagnetic brake is released in advance, the motor can be started rotating more
quickly. Release the electromagnetic brake at least 10 ms before starting the motor.
•If a current is applied between the two electromagnetic brake lead wires (orange) when the
motor is stopped, the electromagnetic brake is released and the motor shaft can be rotated
easily by hand.

zSimplied connection
Note Connection cannot be simplied for vertical drive operation and three-phase motors.
When operating the motor and the electromagnetic brake with a single switch (contact), connect the wiring as
shown in the gure below.
However, since the magnetic energy of the motor aects the electromagnetic brake windings, the braking time
is extended by approximately 50 ms compared to the connection diagram on p.18, causing the overrun to
increase.

Insulate all the wire connections, such as the connection between the motor and the power supply. Use the
Protective Earth Terminal to ground the motor. For safety, install a breaker in the power supply line.
The motor rotates in the clockwise direction (CW) if connected as the connection diagram below.
Changing the connection for any two wires of R, S, or T will rotate in the counterclockwise (CCW).
Use lead wires for power supply equal to or thicker than the lead wire size of AWG 20 (0.5 mm2).
