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 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.
When an ambient temperature is low, since the load torque may
increase by the viscosity increment of the oil seal or grease, the motor
starting may take a long time or the motor rotation speed may fall.
Use a supplied capacitor, and always keep it connected even after the
motor is started.
Do not forcibly stop the shaft rotation of gearhead by an external
force. Stopping in such a way may cause impact, leading to damage to
the gearhead.
