3.1 ENVIRONMENTAL REQUIREMENTS OUTSIDE THE
CABINET
3.1.1 Environmental Conditions outside the Cabinet
The peripheral units and the control unit have been designed on the
assumption that they are housed in closed cabinets. In this manual
"cabinet" refers to the following:
• Cabinet manufactured by the machine tool builder for housing
the control unit or peripheral units;
• Operation pendant, manufactured by the machine tool builder,
for housing the LCD/MDI unit or operator's panel.
• Equivalent to the above.
The environmental conditions when installing these cabinets shall
conform to the following table. Section 3.3 describes the installation
and design conditions of a cabinet satisfying these conditions.
Operating 0°C to 45°C
Storage, Transport -20°C to 60°C
Ambient
temperature of
the cabinet
Temperature change 0.3°C/minute or less
Normal 75%RH or less, no condensation
Humidity
Short period
(less than 1 month)
95%RH or less, no condensation
Operating 0.5G or less
Vibration
Non-operating 1.0G or less
Operating Up to 1000 m (Note) Meters above
sea level
Non-operating Up to 12000 m
Environment
Normal machine shop environment
(The environment must be considered if the cabinets
are in a location where the density of dust, coolant,
organic solvent, and/or corrosive gas is relatively high.)
NOTE
If the CNC is installed 1000 m or higher above sea level, the allowable upper
ambient temperature of the CNC in the cabinet is changed as follows.
Assume that the allowable upper ambient temperature of the CNC in the cabinet
installed 1000 m or higher above sea level decreases by 1.0°C for every 100 m rise
in altitude.
Example)
The upper allowable ambient temperature of the CNC in the cabinet installed
1750 m above sea level is:
55°C - 1750/100 × 1.0°C = 47.5°C
Therefore, the allowable ambient temperature range is from 0°C to 47.5°C.
When a hard disk is used, there are the following installation conditions:
Meters above sea level (operating): -60 to 3000 m
Meters above sea level (non-operating): -60 to 12000 m
