Shock and Vibration
Table 2-1. 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 2-1. 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 2-1.
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.
