1. Precautions
1.1 Precautions for Installation
•Do not use in a place where there is ammable gas and/or corrosive gas.
•When installing the motor into your equipment, ensure that the motor lead wires are xed and do not move.
In addition, do not apply any pressure to these lead wires.
•The motor is Class І equipment. Install the motor so as to avoid contact with hands, or ground it to prevent the risk of electric shock.
•The motor housing must be mounted with a screw and spring washer to the ground point of the equipment.
•Installation must be performed by a qualied installer.
1.2 Precautions for Operation
•The Motor case temperature can exceed 70°C (depending on operation conditions). In case motor is
accessible during operation, please attach the following warning label so that it is clearly visible.
•Always turn o󰀨 the power to the motor before conducting checks or performing work on the motor.
Thermally protected motors will restart automatically when motor temperature falls bellow a certain level.
•Do not use the electromagnetic brake of the motor as a safety brake.
In the event the overheat protection device (thermal protector) is triggered, the load will not be held in position.
A safety device should be provided separately.

4.1 Mounting the motor
1) Pinion shaft motor
Motor
Gearhead
Screws provided
with gearhead
Mounting
Plate
Drill holes in the mounting plate that match the screws and the motor’s
dimensions.
Attach the motor and gearhead using the screws supplied with the gearhead
(gearhead sold separately).
Fasten the screws supplied with the gearhead to the mounting plate. Attach so
that no gaps are left between the motor ange surface and the gearhead pilot
section end surface.
Refer to the gearhead operation manual for further details concerning mounting
(gearhead sold separately).
Note: Use the gearhead of the same type of pinion shaft as the motor.
2) Motor with cooling fan
When mounting a motor with a cooling fan onto a device, open a ventilation hole or leave 10 millimeters (0.4 inches) or more behind the fan cover
so that the cooling inlet on the back of the motor cover is not blocked.
4.2 Mounting the capacitor (For only single-phase motors)
4.3
(.169DIA.)
Before mounting the provided capacitor, check that the capacitor’s capacitance matches that stated on the
motor’s name plate.
Use M4 screws to mount the capacitor (screws not provided).
Note -Do not let the screw fastening torque exceed 1 N·m (10 kgfcm) to prevent damage to the mounting feet.
-Mount capacitor at least 10 cm (3.94 inches) away from the motor. If it is located closer, the life of the
capacitor will be shortened.
∗ Dimensions in millimeters (inches).
4.3 Changing Direction of the Cable Outlet

The capacitor internal wiring is as follows:
Capacitor terminals are internally electrically connected in twos; A−B and C−D for easy connection.
For easy to install terminals use 187 series FASTON Terminals (TE Connectivity).
For lead wire connection, use one lead wire for each individual terminal.

Note: Wiring cannot be simplied for vertical drive applications or three-phase
motors.
Connection can be simplied by using the connecting diagrams shown below
when changing the swich RUN/STOP of the motor and the electromagnetic brake
by one swich. Using the connection shown below, however, results in a 50msec.
increase in braking time over that of the basic connection with a corresponding
increase in overrun. The reason for this is that an electromagnetic energy of motor
electromagnetic brake, so that the electromagnetic continues to operate for about
50msec. even though the swich SW1 has been turned o󰀨. The brake thus takes
longer to engage.

5.2 Operation
Note: -Make sure that the motor case temperature does not exceed 90°C (194°F) during motor operation.
Operating the motor above 90°C (194°F) will shorten the life of the coil and the ball bearings.
Motor case temperature can be measured by fastening a thermometer to the motor’s surface, or with thermo-tape.
Thermal Class: 130 (B)
-Be sure to use the capacitor that comes standard with your motor.
Keep the capacitor connected all the time even after the motor has been started.

Starting and Stopping
SW1 operates motor and electromagnetic brake action.
Motor will rotate when SW1 is switched simultaneously to ON (short circuit). When SW1 is swiched simultaneously to OFF (open),
the motor stops immediately by electromagnetic brake and holds the load.
Note: When operating the electromagnetic brake, this may make a friction noise because this is the braking system by friction,
but this is not a problem.
Direction of Rotation
[Single-phase motor] To rotate the motor in a clockwise (CW) direction, swich SW2 to CW.
To rotate it in a counter-clockwise (CCW) direction, swich SW2 to CCW.
[Three-phase motor] To change the direction of rotation, change any two connections between U, V and W.
Other ways of operating
Note: When driving a vertical load, this method cannot be applied because this may cause the load to fall.
•Hastening the motor’s starting time
If the electromagnetic brake is left release, the motor can be started much faster.
Optimum timing for release of the brake is at least 10msec. before starting up the motor.
•Releasing Electromagnetic brake
If you wish to release the brake while the motor is stopped, apply voltage between only two orange lead wires.
The electromagnetic brake is released and the motor shaft can be rotated easily by hand.
6. Time Rating
Induction motors have a continuous rating.
Reversible motors have a 30 minutes rating. "30 min" is indicated on the nameplate.
7. Locked rotor burnout protection
This motor is equipped with one of two methods to prevent burning the motor as a result of abnormal heating.
Thermal protection ("TP" is stamped on the motor name plate)
The motor has an "auto reset" type thermal protector built into its motor coil. When the motor reaches a predetermined temperature, the
internal thermal protector is activated and the motor is stopped.
In this stage, the electromagnetic brake is left released so that the motor does not keep hold of the load. Adopt another safety measure.
Always turn the power o󰀨 before performing inspections.
Thermal protector activation range:
Power is turned o󰀨 at 130°C (266°F) ±5°C (9°F)
Power is turned back on at 85°C (185°F) ±20°C (36°F)

hot (motor case temperature
exceeds 90°C (194°F))
1. Is the correct voltage being supplied to the motor?
2. Does the ambient temperature exceed the permissible range?
3. For a single-phase motor is the provided capacitor connected as shown in the wiring
diagram of page 4?
