BR excess temperature

What does A793 mean?

The brake resistor temperature has exceeded the warning limit defined by parameter 43.12. This indicates the resistor is overheating, potentially due to excessive braking duty or improper dimensioning. Continued operation risks damage to the resistor or associated components.

Additional Steps

Steps 1–2 are listed in Priority Fix.

1. 3

   Review the warning limit setting in parameter 43.12 (Brake resistor warning limit).

2. 4

   Verify that the brake resistor has been correctly dimensioned for the application and that the braking cycle meets allowed limits.
