Servomotor Specifications and Dimensional Drawings
3.9.4 Impact Resistance
Mount the servomotor with the axis horizontal. The servomotor will withstand the following vertical impacts:
3.9.5 Vibration Resistance
Mount the servomotor with the axis horizontal. The servomotor will withstand the following vibration accelera-
tion in three directions: Vertical, side to side, and front to back.
3.9.6 Vibration Class
The vibration class at rated motor speed is as follows:
• Vibration Class: 15 μm or below
3.9.7 Enclosure
* Excluding the shaft opening.
3.9.8 Heating Conditions
Note that when the flange face is smaller, the continuous allowable torque is reduced.
Make sure there is no confined heat around the servomotors. (Do not use servomotors in a closed, unventilated
space.)
