a. Operating

–1,000 to +10,000 feet (–305 to +3,048 meters)

b. Non-operating

–1,000 to +40,000 feet (–305 to +12,192 meters)

Shock and vibration limits specified in this document are measured directly on the drive chassis. If the drive is 
installed in an enclosure to which the stated shock and/or vibration criteria is applied, resonances may occur 
internally to the enclosure resulting in drive movement in excess of the stated limits. If this situation is apparent, 
it may be necessary to modify the enclosure to minimize drive movement.

The limits of shock and vibration defined within this document are specified with the drive mounted by any of 
the four methods shown in Figure 6, and in accordance with the restrictions of Section 8.4.

a. Operating—normal

The drive, as installed for normal operation, shall operate error free while subjected to intermittent shock not 
exceeding:

• 40 Gs at a duration of 11ms (half sinewave)

• 25 Gs at a duration of 2ms (half sinewave)

Shock may be applied in the X, Y, or Z axis. Shock is not to be repeated more than once every 2 seconds.

b. Non-operating

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

The drive subjected to nonrepetitive shock not exceeding the three values below, shall not exhibit device 
damage or performance degradation. 

• 80 Gs at a duration of 11ms (half sinewave)

• 400 Gs at a duration of 2ms (half sinewave)

• 300

Gs at a duration of 0.5ms (half sinewave)

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