2.9.5.1 Operating shock
The drives comply with the performance levels specified in this document when subjected to a maximum oper-
ating shock of 70 Gs (Read) and 30 Gs (Write) based on half-sine shock pulses of 2 msec. Shocks should not
be repeated more than two times per second.
2.9.5.2 Non-operating shock
The non-operating shock level that the drive can experience without incurring physical damage or degradation
in performance when subsequently put into operation is 350 Gs based on a nonrepetitive half-sine shock pulse
of 2 msec duration.
2.9.6

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.
2.9.6.1 Operating vibration
The maximum vibration levels that the drive may experience while meeting the performance standards speci-
fied in this document are specified below
5Hz to 350 Hz 0.50 Gs
350Hz to 500 Hz 0.25 Gs
2.9.6.2 Non-operating vibration
The maximum non-operating vibration levels that the drive may experience without incurring physical damage
or degradation in performance when subsequently put into operation are specified below.
5Hz to 350Hz 5.0 Gs
