3 Servomotor Specifications and Dimensional Drawings
3.3.3 Mechanical Tolerance
3-14
3.3.3 Mechanical Tolerance
The following table shows tolerances for the servomotor’s output shaft and installation area. For more details on
tolerances, refer to the dimensional drawing of the individual servomotor.
3.3.4 Direction of Servomotor Rotation
Positive rotation of the servomotor is counterclockwise when viewed from the load.
3.3.5 Impact Resistance
Mount the servomotor with the axis horizontal. The servomotor will withstand the following vertical impacts:
• Impact acceleration: 490 m/s
2
• Impact occurrences: 2
3.3.6 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. The amount of vibration the servomotor endures
will vary depending on the application. Check the vibration acceleration being applied to your servomotor for
each application.
• Vibration acceleration: 24.5 m/s
