MITSUBISHI CNC
4-4 Drive unit
4-4-1 Environmental conditions
(Note) When installing the machine at 1,000m or more above sea level, the heat
dissipation characteristics will drop as the altitude increases. The upper limit of
the ambient temperature drops 1°C with every 100m increase in altitude.
(The ambient temperature at an altitude of 2,000m is between 0 and 45°C.)
4-4-2 Heating value
Each heating value is calculated with the following values.
The values for the servo drive unit apply at the stall output. The values for the spindle drive unit apply for the
continuous rated output.
Environment Conditions
Ambient temperature 0°C to +55°C (with no freezing)
Ambient humidity 90% RH or less (with no dew condensation)
Storage temperature -15°C to +70°C (with no freezing)
Storage humidity 90% RH or less (with no dew condensation)
Atmosphere
Indoors (no direct sunlight);
no corrosive gas, inflammable gas, oil mist, dust or conductive fine particles

1. Design the panel's heating value taking the actual axis operation (load rate) into consideration.
2.The heating values in the above tables are calculated with the following load rates.
