If the error persists after a restart, consider swapping the control module with another axis to see if the error moves with it. Monitor Load:

Does the error occur , or only when the axis begins to move ?

Wait for the internal capacitors to drain safely. Power back up to see if the fault clears or persists. Step 2: Inspect Electrical Connections and Cabling

This error stems from a break in the electrical, mechanical, or internal communication loops required by the current controller. 1. Broken Motor Connections or Missing Phases

If you encounter this error, follow these steps in order of complexity: Step 1: Check External Connections

: If the error migrates to the new axis channel on your CNC display, your issue is a physical motor winding failure or an intermittent cable break that only opens up under movement stress.

: A broken or disconnected motor power cable (the orange cable) or a loose connector.

If the fault , the internal IGBTs or current-sensing circuits are defective. The power section needs repair.

If the error persists after checking cables and mechanics, the power section or control module likely requires professional repair or replacement.

A missing or dropped phase (U, V, or W) along the power line.
