What does A794 mean?

One or more of the brake resistor data settings (parameters 43.08 … 43.10) are incorrect or missing. This prevents the drive from correctly calculating brake resistor operation and protection. Incorrect data can lead to improper braking or resistor damage.

Additional Steps

Steps 1–2 are listed in Priority Fix.

  1. 3

    - If 0000 0002 (Thermal time constant not given), check parameter 43.08.

  2. 4

    - If 0000 0003 (Maximum continuous power not given), check parameter 43.09.
