2.10.5Shock

All shock specifications assume that the drive is mounted securely with the input shock applied at the drive mount- ing screws. Shock may be applied in the X, Y or Z axis.

2.10.5.1Operating shock

These drives comply with the performance levels specified in this document when subjected to a maximum operat- ing shock of 350 Gs based on half-sine shock pulses of 2 msec. Shocks should not be repeated more than two times per second.

2.10.5.2Nonoperating shock

The nonoperating shock level that the drive can experience without incurring physical damage or degradation in performance when subsequently put into operation is 800 Gs based on a nonrepetitive half-sine shock pulse of 2 msec duration.

The nonoperating shock level that the drive can experience without incurring physical damage or degradation in performance when subsequently put into operation is 800 Gs based on a nonrepetitive half-sine shock pulse of 1 msec duration.

The nonoperating shock level that the drive can experience without incurring physical damage or degradation in performance when subsequently put into operation is 600 Gs based on a nonrepetitive half-sine shock pulse of 0.5 msec duration.

2.10.6Vibration

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.

2.10.6.1Operating vibration

The maximum vibration levels that the drive may experience while meeting the performance standards specified in this document are specified below.

5–500 Hz

1.0 Gs (0 to peak). Max displacement may apply below 10 Hz.

2.10.6.2Nonoperating vibration

The maximum nonoperating vibration levels that the drive may experience without incurring physical damage or degradation in performance when subsequently put into operation are specified below.

5–500 Hz:

5.0 Gs (0 to peak). Max displacement may apply below 22 Hz.

2.11Acoustics

Drive emission of sound is measured consistent with the ECMA-74 and its’ referenced standards. Testing is con- ducted at room temperature (approximately 25°C). Emission levels are reported as the total A-weighted sound power levels for steady state, idle, and active seek modes of operation.
