a. Operating - normal

The drive as installed for normal operation, shall comply with the complete specified performance while 
subjected to continuous vibration not exceeding

5-22 Hz @ 0.25 G (zero to peak)

 

22-350 Hz @ 0.50 G (zero to peak)

 

350-500 Hz @ 0.25 G (zero to peak)

Vibration may be applied in the X, Y, or Z axis.

Operating normal translational random flat profile

10 - 500 Hz

0.5 G RMS (grams root mean square)

b. Operating - abnormal

Equipment as installed for normal operation shall not incur physical damage while subjected to periodic 
vibration not exceeding:

15 minutes of duration at major resonant frequency

0-22 Hz @ 0.25 G (X, Y, or Z axis, zero to peak)

 

22-350 Hz @ 0.50 G (X, Y, or Z axis, zero to peak)

 

350-500 Hz @ 0.25 G (X, Y, or Z axis, zero to peak)

Vibration occurring at these levels may degrade operational performance during the abnormal vibration 
period. Specified operational performance will continue when normal operating vibration levels are 
resumed. This assumes system recovery routines are available.

Operating abnormal translational random flat profile

10 - 500 Hz

1.2 G RMS (grams root mean square)

c. Non-operating

The limits of non-operating vibration shall apply to all conditions of handling and transportation. This 
includes both isolated drives and integrated drives.

The drive shall not incur physical damage or degraded performance as a result of continuous vibration not 
exceeding

5-22 Hz @ 0.25 G (zero to peak)

 

22-350 Hz @ 5.00 G (zero to peak)

 

350-500 Hz @ 1.0 G (zero to peak)

Vibration may be applied in the X, Y, or Z axis.

Non-operating translational random flat profile

10 - 500 Hz

1.2 G RMS (grams root mean square)

The drive is designed to operate in a typical office environment with minimal environmental control.
