4-1 Installation Conditions
4-1-2 Servomotors
•
Bevel gears will cause a load to be applied
in the thrust direction depending on the
structural precision, the gear precision, and
temperature changes. Provide appropriate
backlash or take other measures to ensure
that no thrust load is applied which exceeds
specifications.
Bevel gear
Make moveable.
•
Do not put rubber packing on the flange
surface.
•
When connecting to a V-belt or timing belt, consult the maker for belt selection and
tension.
•
A radial load twice the belt tension will be placed on the motor shaft. Do not allow a
radial load exceeding specifications to be placed on the motor shaft due to belt tension.
If an excessive radial load is applied, the motor shaft and bearings may be damaged.
•
Set up a movable pulley between the motor axis and the load axis so that the belt
tension can be adjusted.
Pulley for tension adjustment
(Make adjustable.)

Water and Drip Resistance
The enclosure ratings for the Servomotors are as follows:
IP55 (except for through-shaft parts and cable exit holes)
Other Precautions
Take measures to prevent the shaft from rusting. The shafts are coated with anti-rust oil
when shipped, but anti-rust oil or grease should also be applied when connecting the
shaft to a load.
WARNING
Do not apply commercial power directly to the Servomotor.
Applying commercial power directly will burn out the motor coils.
Do not attempt to disassemble, repair, or modify any Units. Any attempts to do so
may result in electric shock or other injury.
