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 significantly deteriorate the coils and
ball bearings of the motor and shorten the motor's life span. Motor
case temperature can be measured by fixing a thermometer on
the motor surface. It can also be measured using thermo tape or a
thermocouple.
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 specified value, the thermal protector is
activated and the motor is stopped.
Always turn the power off 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
office.
Phenomena
Check items
Motor does not rotate.
Motor sometimes rotates
and stops.
•
Check the power supply voltage.
•
Connect the power supply and the motor correctly.
•
Connect the supplied capacitor correctly.
•
If terminal blocks or crimp terminals are used,
check them for poor connection.
•
Keep the load at or below the allowable value.
The motor rotates in the
direction opposite to the
specified direction.
•
Connect the supplied capacitor correctly.
•
The connection varies depending on the gear
ratio of the gearhead.
•
The rotation direction is as viewed from the
output shaft end. Check the reference direction.
Motor temperature
abnormally high
[Motor case temperature
exceeds 90 °C (194 °F) ]
•
Check the power supply voltage.
•
With a single-phase motor, connect the supplied
capacitor correctly.
•
Review the ventilation condition.
Noisy operation
•
Assemble the motor and gearhead correctly.
•
Assemble a gearhead of the same pinion type as
the motor.
