Effective altitude (sea level)
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
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 8, and in accordance with the restrictions of Section 11.3.

7.4.4.1
Shock
a. Operating—normal
The drive, as installed for normal operation, shall operate error free while subjected to intermittent shock not
exceeding 15 Gs at a maximum duration of 11 msec (half sinewave). The drive, as installed for normal
operation, shall operate error free while subjected to intermittent shock not exceeding 20 Gs at a maximum
duration of 2 msec (half sinewave). Shock may be applied in the X, Y, or Z axis.
exceeding 15 Gs at a maximum duration of 11 msec (half sinewave). The drive, as installed for normal
operation, shall operate error free while subjected to intermittent shock not exceeding 20 Gs at a maximum
duration of 2 msec (half sinewave). Shock may be applied in the X, Y, or Z axis.
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 11 msec (half sinewave) and 25 Gs as a maxi-
mum duration of 2 msec (half sinewave). Shock occurring at abnormal 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 two times per second.

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.
