Brake ResistorThe brake resistor is a module capable of absorbing thebrake power generated in regenerative braking. Thisregenerative braking power increases the intermediatecircuit voltage and a brake chopper ensures that thepower is transmitted to the brake resistor. CT CharacteristicsConstant torque characteristics used for all applicationssuch as conveyor belts, displacement pumps and initialising is carried out (14-22 Operation Mode), thefrequency converter returns to the default Duty CycleAn intermittent duty rating refers to a sequence of dutycycles. Each cycle consists of an on-load and an off-loadperiod. The operation can be either periodic duty or non-periodic parameter settings in 4 set-ups.
