2.11.1Shock

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.

2.11.1.1Operating shock

These drives comply with the performance levels specified in this document when subjected to a maximum operating shock of 300 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 150 Gs.
