What does 04 mean?

Immediate switch-off indicating an issue with the braking system, such as excessive regenerative power, an interrupted braking resistor circuit, a short circuit in the braking resistor circuit, a braking resistor with too high resistance, or a defective brake chopper. A ground fault could also be a contributing factor.

Additional Steps

Steps 1–2 are listed in Priority Fix.

  1. 3

    Verify the technical data (e.g., resistance value) of the braking resistor matches specifications.

  2. 4

    Replace the MOVIDRIVE unit if the internal brake chopper is determined to be defective.

  3. 5

    Check for any ground faults within the braking resistor circuit or associated wiring.
