2.9Environmental specifications

2.9.1Drive case temperature

Above 1,000 feet (305 meters), the maximum temperature is derated linearly to 112°F (44°C) at 10,000 feet (3,048 meters).

Drive case temperature should be measured at the location indicated in Figure 5 on page 19.

Operating (Drive case temperature)

0° to 75°C (32° to 167°F)

 

 

Nonoperating (Ambient *)

–40° to 70°C (–40° to 158°F)

 

 

* Ambient temperature is defined as the temperature of the environment immediately surrounding the drive.

2.9.2Temperature gradient

Operating:

20°C per hour (68°F per hour max), without condensation

 

 

Nonoperating:

30°C per hour (86°F per hour max)

 

 

2.9.3Humidity

2.9.3.1Relative humidity

Operating:

5% to 90% noncondensing (30% per hour max)

 

 

Nonoperating:

5% to 95% noncondensing (30% per hour max)

 

 

2.9.3.2Wet bulb temperature

Operating:

37.7°C

(99.9°F max)

 

 

 

Nonoperating:

40.0°C

(104°F max)

 

 

 

2.9.4Altitude

Operating:

–60.96 m to 3,048 m (–200 ft. to 10,000+ ft.)

 

 

Nonoperating:

–60.96 m to 12,192 m (–200 ft. to 40,000+ ft.)

 

 

2.9.5Shock

All shock specifications assume that the drive is mounted securely with the input shock applied at the drive mounting screws. Shock may be applied in the X, Y or Z axis.

2.9.5.1Operating shock

The drives comply with the performance levels specified in this document when subjected to a maximum oper- ating shock of 63 Gs based on half-sine shock pulses of 2 msec. Shocks should not be repeated more than two times per second.

2.9.5.2Nonoperating shock

The nonoperating shock level that the drive can experience without incurring physical damage or degradation in performance when subsequently put into operation is 350 Gs based on a nonrepetitive half-sine shock pulse of 2 msec duration.
