Swept Sine Vibration
The drive will operate without hard errors when subjected to the swept sine vibration of 1.0 G peak from 5
to 300 hz in the x- and y direction. For input in the z-direction, an input of 1.0 G peak amplitude can be
applied from 5 hz to 250 hz, the amplitude at 300 hz is 0.5 G peak. Linear interpolation is used to deter-
mine the acceleration levels between 250 hz and 300 hz.
The test will consist of a sweep from 5 to 300 hz and back to 5 hz. The sweep rate will be one hz per
second.
Note: 1.0 G acceleration at 5 hz requires 0.78 inch double amplitude displacement.

7.2.3.1 Nonoperating Vibration

No damage will occur as long as vibration at the un-packaged drive in all three directions defined above does
not exceed the levels defined in the table below. The test will consist of a sweep from 5 hz to 200 hz and
back to 5 hz at a sweep rate of eight decades per hour.
