2.10.2 Selection of braking resistor Power
Theoretically, braking Power is consistent with braking Power.But in
consideration of the 70 percent derating,please refer to the formula
0.7*Pr=Pb*D, Pr refers to the resistor Power, D refers to braking
frequency(Which is the regeneration process accounting for the proportion of
the whole working process).For example, the braking frequency of elevator is
between 20% to 30%, the winding and unwinding is between 20% to 30%.The
centrifuge is between 50% to 60%, Occasional braking load is 5%. Injection
molding machine braking load is 10%.
