Install the motor to a mounting plate of the following size or larger, so that the motor case temperature will not
exceed 90 °C (194 °F).
The temperature inside the motor can be monitored using the support software or the host controller.

5-3 Installing a load

Combination type-parallel shaft gearhead, round shaft type
When installing a load on the motor or the gearhead, pay attention to the following points.
•
Align the center axis of the motor output shaft or the gearhead output shaft with that of the load.
•
A key slot is provided on the output shaft of each combination type-parallel shaft gearhead. Form a key slot on the
load side and secure the load using the parallel key.
•
When coupling the motor or the gearhead with a load, pay attention to centering, belt tension, parallelism of
pulleys, etc. Also, rmly secure the tightening screws of the coupling or pulleys.
•
When installing a load, do not damage the motor output shaft (gearhead output shaft) or bearings. Installing
the load forcibly with a hammer or the like may break the bearings. Do not apply any excessive force to the
output shaft.
•
Do not modify or machine the output shaft of the motor or gearhead. This may damage the bearing, resulting
in damage to the motor or gearhead.
When using the output shaft end tapped hole of a gearhead
Use a tapped hole provided at the end of the output shaft as an auxiliary
means for preventing the transfer mechanism from disengaging.
