Suggested braking resistance specification parameters
Braking resistance value and power in the chart are decided according to common inertia load and intermittent braking
mode. While used in large inertia occasion or long time frequent brake occasion, please adjust resistance value and
power according to the inverter specification and the rated parameter of braking unit. If any problem, please consult
