Braking resistor phase failure

What does F06922 mean?

This fault indicates a detected phase failure in one of the braking resistors. Depending on the fault value (U, V, or W), a specific phase's feeder cable may be open or disconnected. This can impair the drive's ability to dissipate regenerative energy, potentially leading to overvoltage faults or control issues.

Complete Troubleshooting Guide

1. 1

   Visually inspect the feeder cables for any signs of physical damage or insulation degradation.

2. 2

   Use a multimeter to check the continuity and resistance of each feeder cable to the braking resistors.

3. 3

   Ensure all cable connections to the braking resistors and the drive are secure and free of corrosion.
