Shock and Vibration
Table 2-4. Shock and Vibration
Operating Vibration
Drives are tested by applying a random excitation in each linear axis, one axis at a time. The drive
incurs no physical damage and no hard errors while subjected to continuous vibration not exceeding
the level listed in Table 2-4. Operating performance may degrade during periods of exposure to
continuous vibration.
Non-Operating Vibration
Note
: This specification applies to handling and transportation of unmounted drives.
Drives are tested by applying a random excitation in each linear axis, one axis at a time. The drive
incurs no physical damage when subjected to continuous vibration not exceeding the level listed in
Table 2-4.
Packaged Shock and Vibration
The shipping packaging is designed to meet the National/International Safe Transit Association (N/
ISTA) standards for packaged products. The drive incurs no physical damage when subjected to the N/
ISTA standards.
