Servo Gun Setup - Servogun Diagnosis Package

In this video, we will go over FANUC’s Servo Gun Diagnosis Package, an advanced software option designed to help maintain the long-term health and performance of your servo weld gun. This package is focused on predictive maintenance, giving us the ability to monitor changes in friction and pressure over time and take proactive steps before issues impact weld quality or production efficiency.

We begin by reviewing the prerequisites for using this package, including having a fully operational servo gun that has been mastered, auto-tuned, and pressure calibrated. From there, we’ll explore the two core functions included in the package: Servo Gun Diagnosis and Pressure Check. These features work together to detect changes in gun behavior and alert us when it’s time to inspect or adjust settings.

Here’s what we’ll cover in the video:

• Requirements before starting:
  • Servo gun added at controlled start
  • Mastering and auto-tuning completed
  • Pressure calibration performed
• What you will learn:
  • How Servo Gun Diagnosis monitors disturbance torque during gun motion
  • How to set tolerances and configure outputs for alerts
  • How Pressure Check compares feedback against baseline data and adjusts pressure automatically
  • Best practices for running diagnostics and interpreting results
  • Steps to integrate alerts with your PLC for seamless communication

We’ll also walk through creating a sample program, setting up thresholds, and determining the right intervals for running diagnostics. You’ll see how these tools act as change detectors, helping us maintain weld integrity and avoid costly downtime. Pressure Check adds another layer of protection by automatically adjusting torque to maintain critical weld pressure within tolerance, ensuring consistent performance over the life of the servo gun.

By the end of this session, you’ll understand how FANUC’s Servo Gun Diagnosis Package supports predictive maintenance strategies for spot welding robots. Whether you’re looking to improve reliability, reduce unplanned downtime, or optimize your maintenance schedule, this video provides the insights you need to keep your servo gun operating at its best.
