What is the primary function of 'error handling' in a FANUC robot program?

The primary function of 'error handling' in a FANUC robot program is to detect and respond to faults. This aspect is crucial in robotic systems, as it ensures that the robot can identify issues that arise during operation, such as mechanical failures, communication errors, or unexpected interruptions. By integrating effective error handling procedures, a robot can not only stop operations safely when a fault occurs but also take predefined actions to mitigate the impact of that fault, which might include logging the error, notifying operators, or even attempting to correct the issue automatically.

Implementing robust error handling enhances the reliability and safety of robotic operations, allowing for smoother workflows and minimizing downtime. This capability is vital in industrial settings, where consistency and safety are paramount, and any disruptions can lead to significant losses. Thus, the focus on detecting and responding to faults is essential to maintaining operational efficiency and ensuring the longevity of the robot's functionality.
