half-sine shock pulses of 11 msec, as specified in MIL-STD-202F).
Shocks are not to be repeated more than two times per second.
1.14.2 Nonoperating shock
The nonoperating shock level that the drive can experience without
incurring physical damage or degradation in performance when sub-
sequently put into operation is 200 Gs (based on repetitive half-sine
shock pulses of 2-msec duration, as defined in MIL-STD-202F).
1.14.3 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)
1.14.4 Nonoperating vibration
The following table lists the maximum nonoperating vibration that the
drive may experience without incurring physical damage or degradation
in performance when put into operation.
5–22 Hz 0.081-inch displacement (peak to peak)
22–350 Hz 2.00 Gs acceleration (zero to peak)
1.14.5 Acoustics
This table shows the overall A-weighted acoustic sound power and sound
pressure levels for the drives. All measurements are generally consistent
with ISO document 7779. Acoustic measurements are taken under
essentially free-field conditions over a reflecting plane. The drive is
oriented with the top cover up for all tests.
