10. Operating environment
Operating temperature
Operating temperature 0°C to 40°C
The ambient temperature should be maintained within a range of 0 to 40°C during operation.
This is the range in which continuous operation of the robot controller is guaranteed according
to the initial specifications. If the robot controller is installed in a narrow space, then heat
generated from the controller itself and from peripheral equipment may drive the temperature
above the allowable operating temperature range. This may result in thermal runaway or
malfunctions and may lower component performance along with shortening their useful service
life. So be sure to install the controller in locations with a vent having a natural air flow. If this
proves insufficient, provide forced air-cooling.
Storage temperature
Storage temperature -10°C to 65°C
The controller should be stored in a location at an ambient temperature between -10 and
+65°C when not being used. If the robot controller is stored in a location at high temperatures
for extended periods, deterioration of the electronic components may occur and the memory
backup time may decrease.
Operating humidity
Operating humidity 35% to 85% RH (no condensation)
The ambient humidity of the robot controller should be 35% to 85% RH (no condensation) in
order to guarantee continuous operation within the initial specifications. Installing the robot
controller inside an air-conditioned or cooled housing is recommended when the ambient
humidity is higher than 85% or when condensation occurs.
Storage humidity
Storage humidity Below 95% RH (no condensation)
The controller should be stored in a location at an ambient humidity below 95% RH (no
condensation) when not being used. If the robot controller is stored in a location at high
humidity for an extended period of time, rust may form on the electronic components.
Vibration and shock
Do not apply strong shocks to the controller. Do not install the controller in locations subject to
large vibrations or shocks. The controller may malfunction or break down if subjected to large
vibrations or shocks.
Environments
The controller is not designed to meet explosion-proof, dust-proof, and drip-proof
specifications, and so do not use it in the following locations. If used in these locations,
component corrosion, improper installation, or fire may result.
1) Environments containing combustible gases or dust particles, or flammable liquids, etc.
2) Environments where conductive substances such as metal cutting chips are present.
3) Environments where water, cutting water, oils, dust, metal particles, or organic solvents
are present.
