Brake resistor power limit

What does 26 mean?

The power transmitted to the brake resistor, calculated as an average over the last 120 seconds, exceeds 90% of its capacity. If option [2] Trip is selected in parameter 2-13 Brake Power Monitoring, the frequency converter trips when dissipated braking power reaches 100%.

Additional Steps

Steps 1–2 are listed in Priority Fix.

1. 3

   Extend deceleration ramp times to reduce the peak power dissipated by the brake resistor.

2. 4

   Ensure the brake resistor has adequate ventilation and is not operating in an excessively hot environment.
