3.5 Mechanical Characteristics
• Number of Impacts: 2
Since a precision detector is attached to the shaft at the end opposite the load end, do not subject
the shaft to direct impact as this may damage the encoder.

3.5.6 Vibration Resistance
The Servomotor will withstand a vibration acceleration of 24.5 m/s2 (2.5 G) in the vertical, trans-
verse, and longitudinal directions
(See Fig. 3.9)
when the axis of the Servomotor is mounted hor-
izontally.

3.5.7 Vibration Class
The vibration class of the AC Servomotor is 15 µm or below at the rated speed
(See Fig. 3.10).

SGMEI Servomotors have a precision encoder on the end of the shaft opposite the load. Do not
apply shock directly to the shaft; direct shock can damage this encoder.
