Impact Resistance; Vibration Resistance; Vibration Class - YASKAWA SGM Series User Manual

3.5.5 Impact Resistance

The Servomotor will withstand two vertical impacts at an impact acceleration of 98 m/s
Fig. 3.8.) when the axis of the Servomotor is mounted horizontally.
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.
Figure 3.8

3.5.6 Vibration Resistance

The Servomotor will withstand a vibration acceleration of 24.5 m/s
and longitudinal directions (See Fig. 3.9) when the axis of the Servomotor is mounted horizontal-
ly.

3.5.7 Vibration Class

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