Cause : Brake Resistor Power Limit - 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 parameter 2-11 Brake Resistor (ohm).
- The warning is active when the dissipated braking power is higher than the value set in parameter 2-12 Brake Power Limit (kW).
- The drive trips if the warning persists for 1200 s. Decrease brake energy via lower speed or longer ramp time.
