 Installing a load to the solid shaft type
The shaft of the gearhead has been machined to an outer diameter tolerance
of h7 and is provided with a key slot for connecting the transmission parts.
When connecting the transmission parts, ensure that the shaft and parts have a
clearance t, and always x the parallel key to the output shaft with a screw to
prevent the parts from rattling or spinning. A screw hole is provided at the tip of
the output shaft on solid shaft type. With solid shaft type, use this screw hole as
an auxiliary means for preventing the transmission parts from coming off.

 Operation
When the power is turned on, the motor rotates.
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. However, if the operation is continued for a while, the oil seal or
grease will be warmed up, and the motor can be driven at the normal
rotation speed.
Burnout protection for overload/locked-rotor state
Note When the output shaft is locked or in the case of an overload state,
use an electromagnetic switch in order to prevent the motor from
burning out. When connecting to an inverter, use the electronic
thermal relay function of the inverter.
 When connecting to the power supply
 Always connect an electromagnetic switch. Connect the electromagnetic
switch according to the operating manual of the electromagnetic switch.
 Set the motor rated current for the thermal relay.
The motor rated current is described on the motor nameplate.
 For electromagnetic switches, use the products as shown in the chart, or an
equivalent.

 When connecting to the inverter
Be sure to set the electronic thermal relay according to the operating manual of
the inverter. Unless the electronic thermal relay is set, a burnout may result.
When using the motor with an inverter
When the motor is used with connecting an inverter, perform the following
settings to the inverter.
About the setting frequency for when operating the motor, use at 80 Hz or less for
the model 5IK type (100 W) and at 100 Hz or less for the model 7IK type (200 W).

 Notes about when using the motor with an inverter
Use a motor in a condition where an input voltage to the inverter is at 240 VAC or
lower. For the 7IK200VEU type motor, however, use at 415 VAC or lower.
Using the motor in a condition of exceeding these input voltages may cause the
insulation of the motor windings to deteriorate, leading to damage to the motor.
