Operation
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 signicantly 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.
Single-phase motors use a capacitor and keep it connected even
after rotation of the motor has started.
When operating the electromagnetic brake, there may be a
scraping noise because this braking system uses friction, but this is
not a problem.

Motor
Starting and stopping
The SW1 is used for "operation/standstill" of the motor, and "operation/
standstill" of the electromagnetic brake. When the SW1 is turned ON, the
electromagnetic brake is released, and the motor rotates. When the SW1 is
turned OFF, the electromagnetic brake activates, and the motor stops.
If the electromagnetic brake motor is used in vertical drive applications, the
load may move downward. Check the position of the load prior to operation.
Direction of rotation
To rotate the motor in a clockwise (CW) direction, switch SW2 to CW.
To rotate it in a counter-clockwise (CCW) direction, switch SW2 to CCW.
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
Reversible motors have a 30 minutes rating. “30 min” is indicated on the nameplate.
Overheat protection for locked condition
This motor is equipped with one of the two features listed below to prevent the
motor from burning out as a result of abnormal heating which may be caused
by misapplication.
Thermally protected motors
"TP" is marked on the motor nameplate. This motor contains a built-in
automatic return type thermal protector in the motor windings.
If the motor internal temperature exceeds the specied value, the 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.
Operating temperature of thermal protector:
Open (motor standstill) ............ 130±5 °C (266±9 °F)
Close (resuming operation) .... 85±20 °C (185±36 °F)
Impedance protection
"ZP" is stamped on the motor nameplate. The motor has higher coil impedance.
When the motor goes into locked rotor condition due to a malfunction, coil
impedance rises, suppressing input power to the motor and protecting the
motor coil from burnout.
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 oce.
