¶ Axis Driver Indicator Light is Red and Flashing
This page explains how to diagnose and resolve issues when an axis driver indicator light turns red and flashes. It covers what the flashing patterns mean, why the driver enters protection mode, and how to safely restore normal machine operation.
¶ Problem Description
Remove the right-side cover panel to locate the axis drivers. Under normal operating conditions, the status indicator light on the driver should be solid green. If the red indicator light begins to flash, it indicates an abnormality with the driver or motor position.
