A Fanuc control system can start to fail for various reasons. Although they are industrial-grade CNC control devices, they may begin to fail due to wear and tear. These controllers have internal components that fail as time passes. It is often difficult to determine if the unit has failed or is suffering a serious drop in performance. Engineers examine the connections and power supply to determine if the controller has any issues. Though serious problems in Fanuc control units can be easy to detect, simple failures in the controllers can be difficult to track.

What are the Potential Warning Signs?

A common issue in Fanuc control may show up in one of the three ways. First, the process the unit controls may just stop, or the system may slow down or run irregularly. You will also notice performance issues. Such issues require an expert analysis to pinpoint the problem and then fix it. If the unit is malfunctioning, the engineer needs to diagnose the problem and get the controller running as soon as possible. If there is a production slowdown, you need to identify the part that is underperforming. Many components in the unit may end up failing. Fanuc spares suppliers offer obsolete parts that can help you quickly replace the failed components.

Failure Control Failure Points

The root cause of Fanuc Control system failure mostly comes down to a fault in one of the numerous elements that take the signal from the outside device and direct it through a circuit board to another component. From there, it goes to an output device and onwards out from the fanuc control to an element it controls.

A Fanuc controller only works if all of the internal components can process the inputs the device receives and output the correct signal. Internally, the memory, CPU, and communication interface could suffer physical damage or faults due to heavy use and rarely due to age. Environmental conditions and power surges may cause performance problems and outright failure. According to experts, most Fanuc control system failures come down to issues such as failure of a field device or VCD, bad network connections, problems with the power supply, configuration errors, and internal wiring problems.

Like other industrial components, these devices also have a limited life expectancy. While a Fanuc CNC mill’s motor may come with a 10-year service, most business owners adhere to a realistic life expectancy when considering reconditioning or replacing old components. The same principle applies to Fanuc Control. The unit could last up to 20 years, under ideal operating conditions which include a clean environment, low cycle rates, and moderate temperatures.

These variables that affect the service life of the controller and its reliability are mostly external factors. Regular maintenance and adherence to these conditions can significantly extend the lifespan of your Fanuc Control unit. Excessive heat can also cause problems inside the Fanuc Control, which could eventually lead to performance problems. This includes electromagnetic radiation and long-term exposure to heat and moisture.

Bottom Line

Although Fanuc Control units and their internal components are quite reliable and durable, components can fail or malfunction. These units have several major components that could fail in various ways. These issues can be minimized by maintaining the system propeller and keeping a backup of the Fanuc obsolete parts on hand.
