ESD
The ESD specification compliance is determined at room ambient conditions with nominal power
supply settings, unless otherwise specified.

Shock and Vibration
Table 2-1. Shock and Vibration
Operating Vibration
Drives are tested by applying a random or swept sinusoidal excitation in each linear axis, one axis at a
time. The drive incurs no physical damage and no hard errors while operating and 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 capability applies to handling and transportation of unmounted drives.
Drives are tested by applying a random or swept sinusoidal 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.
Drive Generated Vibration
Drives are tested by supporting a single drive horizontally in a free-free state and measuring the side-to-
side vibration. Self vibration may not exceed the level listed in Table 2-1.
