The protective structure rating of the Servomotor is IP67, except for the through-shaft part and connec-
tor pins.
It is IP20 if you use a 30-meter or longer encoder cable.
Use the Servomotor with an oil seal if you use it in an environment where oil drops can adhere to the
through-shaft part. The operating conditions of the Servomotor with an oil seal are as follows:
• Keep the oil level below the lip of the oil seal.
• Prepare a good lubricated condition under which only oil droplets splash on the oil seal.
• If you use the Servomotor with the shaft in upward direction, make sure that no oil accumulates on
the lip of the oil seal.
When you mount a Servomotor onto a small device, be sure to provide enough radiation space on the
mounting area because the heat is radiated from the mounting surface. Otherwise the Servomotor tem-
perature may rise too high. One of the preventive measures is to install a radiator plate between the
motor attachment area and the motor flange. (See the following figure)
Failure to follow this guideline may result in damaging the Servomotor due to a temperature rise.
Refer to
on page 3-43 for the radiator plate specifications.
• The temperature rise depends on the mounting part materials and the installation environment.
Check the actual temperature rise by using a real Servomotor.
• Depending on the environment, such as when the Servomotor is installed near a heating element,
the Servomotor temperature may rise significantly. In this case, take any of the following measures.
a) Lower the load ratio.
b) Review the heat radiation conditions of the Servomotor.
c) Install a cooling fan and apply forced air cooling to the Servomotor.
