7.4.3

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)

7.4.4

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.

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.

The drive subjected to nonrepetitive shock not exceeding 80 Gs at a maximum duration of 11 msec (half

sinewave) shall not exhibit device damage or performance degradation. Shock may be applied in the X, Y,

or Z axis.

The drive subjected to nonrepetitive shock not exceeding 300 Gs at a maximum duration of 2 msec (half

sinewave) does not exhibit device damage or performance degradation. Shock may be applied in the X, Y,

or Z axis.

The drive subjected to nonrepetitive shock not exceeding 150 Gs at a maximum duration of 0.5 msec (half

sinewave) does not exhibit device damage or performance degradation. Shock may be applied in the X, Y,

or Z axis.
