1.8.5 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.

1.8.5.1 Operating shock

These drives comply with the performance levels specified in this docu- ment when subjected to a maximum operating shock of 63 Gs (based on half-sine shock pulses of 2 msec). Shocks should not be repeated more than two times per second.

1.8.5.2 Nonoperating shock

The nonoperating shock level that the drive can experience without incurring physical damage or degradation in performance when subse- quently put into operation is 350 Gs (based on nonrepetitive half-sine shock pulses of 1 and 2 msec duration).

1.8.6 Vibration

All vibration specifications assume that the drive is mounted securely with the input vibration applied at the drive mounting screws. Vibration may be applied in the X, Y or Z axis.
