1.8.4 Altitude
1.8.5 Shock
During shock tests, the drive was 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 are not to 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 300 Gs (based on a nonrepetitive half-sine
shock pulse of 2 msec duration). Shock pulses are defined by MIL-STD-
202F.
1.8.6 Vibration
During vibration tests, the drive was mounted securely with the input
vibration applied at the drive mounting screws. Vibration may be applied
in the X, Y or Z axis.
1.8.6.1 Operating vibration
The following table lists the maximum vibration levels that the drive may
experience while meeting the performance standards specified in this
document.
Operating
–122 m to 3,048 m (–400 ft to 10,000+ ft)
Nonoperating
–122 m to 12,192 m (–400 ft to 40,000+ ft)
5–22 Hz
0.020-inch displacement (peak to peak)
22–350 Hz
0.50 Gs acceleration (zero to peak)
