Brake resistor wiring

What does A792 mean?

A short circuit has been detected in the brake resistor or a fault within the brake chopper itself. This condition prevents the safe dissipation of regenerative energy and can lead to damage to the brake chopper components, potentially causing further drive faults.

Additional Steps

Steps 1–2 are listed in Priority Fix.

1. 3

   Measure the resistance of the brake resistor to ensure it is not shorted internally.
