Cause : Brake Resistor Power Limit comes when the power transmitted to the brake resistor is calculated as a mean value over the last 120 s of run time. The calculation is based on the DC-link voltage and the brake resistor value set in P 3.3.2 Brake Resistor Value.
- The warning is active when the dissipated braking power is higher than the value set in P 3.3.3 Brake Resistor Power Limit. The drive trips if the warning persists for 1200 s.
- Decrease brake energy via lower speed or longer ramp time.
