Electrical devices generate heat during operation, and industrial robots powered by electricity are no exception. Excessive heat can lead to high internal temperatures, accelerating the aging of components and increasing the likelihood of failures. Regularly cleaning the controller’s ventilation openings and fans helps maintain good heat dissipation, which is beneficial for the stable performance of the robot’s electrical components, preventing accidents and extending service life.
Using the FANUC R-30IB robot as an example, this article demonstrates how to disassemble the fan during cleaning (Note: The fan cleaning process must be performed with the controller power turned off.):
1. Fan of the R-30IB A Cabinet Controller
1.1 Ensure that the space between the controller and surrounding equipment meets the requirements.
1.2 Cleaning the fan on the front of the controller door.
1.3 Cleaning the fan behind the controller door.
1.4 Cleaning the fan on the back of the controller.
2. Fan of the R-30IB B Cabinet Controller
2.1 Ensure that the space between the controller and surrounding equipment meets the requirements.
2.2 Cleaning the fan behind the controller door.
2.3 Cleaning the fan on the back of the controller.
3. Fan of the R-30IB MATE Cabinet Controller
3.1 Ensure that the space between the controller and surrounding equipment meets the requirements.
3.2 Cleaning the fan on the front of the controller door.
3.3 Cleaning the fan behind the controller door.
3.4 Cleaning the fan on the back of the controller (this fan is not installed on machines with a load capacity of 5KG or less).
4. Main Control Unit Cooling Fan of the Controller
4.1 It is recommended to regularly replace the DC 24V cooling fan on the main control unit’s backplane inside the controller.
