Note In case of 60 W type and 90 W type, when removing the sheath of
the cable, be careful not to damage the inside lead wire.
 Lead Wire for Power Supply
Use a lead wire of AWG20 (0.5 mm2) or thicker.
 Grounding
For motors without a Protective Earth Terminal, any one of the four mounting bolts
may be used to attach the ground wire to the motor case. If necessary, remove all
paint that may impede conductivity around the bolt mounting hole.
 Simplied connection
Note Wiring cannot be simplied for vertical drive applications or three-
phase motors.
If the “RUN/STOP” operation of the motor and “RUN/STOP” operation of the
electromagnetic brake are controlled via a single switch (contact), connect the lead
wires as shown in the gure below.
Note that the motor’s magnetic energy aects the electromagnetic brake windings,
resulting in a longer braking time than that of the Connection diagram: ①, ② by
approximately 50 ms and thus increased overruns.

Operating
The motor rotates when the power supply is turned on.
For protection against electric shock, do not turn on the power supply until the
wiring is complete.
Note
•Make sure that the motor case temperature does not exceed
90 °C (194 °F) when operating the motor. Operation exceeding case
temperature 90 °C (194 °F) may signicantly deteriorate the coils
and ball bearings of the motor and shorten the motor's life span.
Motor case temperature can be measured by xing a thermometer
on the motor surface. It can also be measured using thermo tape
or a thermocouple.
•Do not perform an operation switching the motor rotation
direction instantaneously with three-phase motors. Doing so may
cause damage to the motor and gearhead.
•Single-phase motors use a capacitor and keep it connected even
after rotation of the motor has 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 switched simultaneously to OFF (open), the motor stops immediately
by electromagnetic brake and holds the load.
Note When operating the electromagnetic brake, there may be a scraping
noise because this braking system uses friction, but this is not a
problem.
The load may move downward in vertical drive applications. Check the position of
the load prior to operation.
 Other ways of operating
zShortening 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 10 ms before starting up the
motor.
zReleasing electromagnetic brake
If you wish to release the brake while the motor is stopped, apply voltage between
only the two orange lead wires. The electromagnetic brake is released and the motor
shaft can be rotated easily by hand.
Time rating
zInduction motors
Induction motors have a continuous rating.
zReversible motors
Reversible motors have a 30 minutes rating. “30 min” is indicated on the nameplate.
Troubleshooting
When the motor cannot be operated correctly, refer to the contents provided in this
section and take appropriate action. If the problem persists, contact your nearest
oce.
