6.4.3Effective altitude (sea level)

a.Operating

–200 to +10,000 feet (–60.96 to +3,048 meters)

b.Non-operating

–200 to +40,000 feet (–60.96 to +12,210 meters)

6.4.4Shock 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 8.3.

6.4.4.1Shock

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). Shock occurring at abnormal levels may promote degraded operational performance during the abnormal shock period. Speci- fied 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 75 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 nonrepetitve shock not exceeding 200 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.
