1.8.4 Altitude

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)

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.

5–22 Hz	0.020-inch displacement (peak to peak)
22–350 Hz	0.50 Gs acceleration (zero to peak)
