Shock and vibration
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 11, and in accordance with the restrictions of Section 11.3.

7.5.4.1
Shock
a. Operating—normal
The drive, as installed for normal operation, shall operate error free while subjected to intermittent shock not
exceeding 70 Gs at a maximum 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.
exceeding 70 Gs at a maximum 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. Operating—abnormal
Equipment, as installed for normal operation, does not incur physical damage while subjected to intermit-
tent shock not exceeding 40 Gs at a maximum duration of 11ms (half sinewave). Shock occurring at abnor-
mal levels may promote degraded operational performance during the abnormal shock period. Specified
operational performance will continue when normal operating shock levels resume. Shock may be applied
in the X, Y, or Z axis. Shock is not to be repeated more than once every 2 seconds.

c. 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 80 Gs at a maximum duration of 11ms (half sine-
wave) shall not exhibit device damage or performance degradation. Shock may be applied in the X, Y, or Z
