Shock
and
Vibration
Table
I-I
lists specified levels for shock and vibration applied to any
of
the three mutually perpendicular
axes (the principal drive base axes). The term "operating" implies that the drive will be fully functional
while being subjected to the shock or vibration level listed during operation. "Non-operating" implies that
there will be no change in performance once the drive is powered up after being subjected to the listed shock
or vibration in the powered-down (non-operating) condition.

In addition, the ProDrive as packaged in the shipping container will withstand drops onto a concrete
surface from 48 inches on all surfaces, six edges and three comers. It will withstand vibration applied to
the container
of
0.5 G, 5-100 Hz (0 to Peak) and
1.5
G, 100-500 Hz (0 to Peak).
