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.

Additional Steps

Steps 1–2 are listed in Priority Fix.

1. 3

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