2.11.1 Shock
All shock specifications assume that the drive is mounted securely with the input shock applied at the drive
mounting screws. Shock may be applied in the X, Y or Z axis.
2.11.1.1 Operating shock
These drives comply with the performance levels specified in this document when subjected to a maximum
operating shock of 200 Gs based on half-sine shock pulses of 2 msec. Shocks should not be repeated more
than two times per second. For 11 msec shock duration, these drives will withstand operating shock up to 110
Gs.
2.11.1.2 Nonoperating shock
The nonoperating shock level that the drive can experience without incurring physical damage or degradation
in performance when subsequently put into operation is 800 Gs based on a nonrepetitive half-sine shock pulse
of 2 msec duration.
The nonoperating shock level that the drive can experience without incurring physical damage or degradation
in performance when subsequently put into operation is 800 Gs based on a nonrepetitive half-sine shock pulse
of 1 msec duration.
The nonoperating shock level that the drive can experience without incurring physical damage or degradation
in performance when subsequently put into operation is 400 Gs based on a nonrepetitive half-sine shock pulse
of 0.5 msec duration.
