This is not a critical machine failure, but rather a . Here is a breakdown of what it means, why it appears, and how to resolve it. If the enclosure door is open while trying

However, running production while this warning is active is highly inefficient, as cycle times will balloon due to capped feedrates. To maintain high productivity and safety:

Unlike critical system alarms that immediately halt all machine motion (E-stops), a warning (denoted by the "WN" prefix on newer FANUC i-Series controls) serves as an informational alert. It signifies that the machine is operating under modified parameters that could affect cycle times, part finishes, or automated sequences. What is the WN57 Warning?

If you are writing a macro and want to check if an operator has left an override active, you can use system variables:
