By carrying out regular planned maintenance your equipment will last longer, reducing costly downtime.
FANUC Robotics offers a wide range of standard and customised maintenance contracts. Our contract duration is typically between 3 and 5 years with maintenance being performed at least once per year depending on your application and work environment.
Our service department will be happy to discuss your robot application with you to determine the best maintenance schedule to suit your requirements.
As with any key production equipment, a Preventative Maintenance program will extend the production life, and ensure you receive maximum utilisation of the robot.
 |
Planned maintenance should be undertaken every 3,850 hours or 12 months, whichever comes first. This will reduce unplanned downtime and help to ensure your robot keeps running. We understand that downtime is lost production !
As part of our Maintenance program, our engineers will check the following items where applicable: - Take a controller memory back up.
- Visual inspection of general robot condition, robot internal harness and robot connection cables.
- Brake operation and overtravel switch operation.
- Repeatability test.
- Check for excessive audible vibration and noise.
- Lubricate as per specification.
- Visual inspection of controller condition and Teach pendant cable
- Check cable connections, cooling fans, power supplies and transformer tappings, emergency stop operation, interlock operation, hand broken operation and teach pendant operation.
- Test and replace RAM and APC batteries, as required.
- Provide report on condition of robot and controller detailing any further action required.

FANUC Robotics offer our customers a Predictive Maintenance service. Our engineers can carry out vibration measurement analysis, robot grease analysis, thermal imaging surveys, and provide a detailed report of our findings.
Thermal Imaging
A thermal imaging survey will be carried out during the robots normal production cycle to ensure an accurate record is taken of the robot and controller's operational condition. This will provide detailed information on any hotspots or potential failure problems such as:
- Motor overload
- Cabling issues
- Overloaded payload causing overheating in the Wrist
- Controller Overheat issues due to blocked vent ducts
- Controller issues due to unbalanced phase / incorrect transformer tapping settings.
Vibration Analysis
A Vibration Trend Analysis enables us to compare current vibration data with the original factory data and histrocial readings giveing an insight into the condition of bearings and gears within the gearboxes. Some examples of problems that can be highlighted are:
- Motor problems
- Gearbox issues –bearings, gear wear, backlash, etc
- Excessive payload
- Loose Robot mounting hardware.
- End of arm tooling issues.
Grease Analysis
A grease analysis measures the amount of steel particulates contained within the grease removed during a Preventative Maintenance Service. This in turn gives an insight to the health of the bearings and gears within the gearboxes.
