System Design
Œ
When connecting to a V-belt or timing belt, consult the maker for belt selection and tension.
Œ
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. If an excessive radial load is applied, the
motor shaft and bearings may be damaged.
Œ
Set up a structure so that the belt tension can be adjusted.

Radiator Plate Installation Conditions
Œ
When the Servomotor is installed in a small space, the Servomotor temperature may rise unless
sufficient surface area is provided to allow heat dissipation from the Servomotor mounting surface.
Take measures such as inserting a radiator plate between the Servomotor mounting surface and
the flange. If radiator plates are not inserted, the motor may be damaged by increased
temperatures. For radiator plate specifications, refer to
3-2 Servomotor Specifications .
Œ
Servomotor heating will depend on the material of the mounting surface and on the installation
environment. Be sure to check the Servomotor temperature under actual operating conditions.
Œ
The Servomotor temperature may rise sharply if the Servomotor is installed in an environment
such as near a heat source. Take the following countermeasures as required by the installation
environment.
Œ
Reduce the load ratio.
Œ
Modify the Servomotor's heat dissipation conditions.
Œ
Forcibly cool the Servomotor by installing a cooling fan.

Water and Drip Resistance
Œ
The protective structure for the Servomotors is as follows:
IP65 (except for through-shaft parts and cable outlets)
„
Countermeasures against Oil
When using the Servo Motor in an environment in which the shaft through-hole is exposed to oil
spray, use a Servomotor with an oil seal. The operating conditions for a Servomotor with an oil seal
are as follows:
Œ
Keep the oil level below the lip of the oil seal.
Œ
Set up good lubricating conditions so that any oil spray falls on the oil seal.
Œ
If the Servomotor is used with the shaft pointing upwards, be careful to not allow oil to accumulate
at the lip of the oil seal.
