    (as part of the total cycle time) Danfoss offers brake resistors with duty cycle of 5%, 10% and 40% suitable for use with the FC202 AQUA drive series. If a 10% duty cycle resistor is applied, this is able of absorbing braking power upto 10% of the cycle time with the remaining 90% being used to dissipate heat from the resistor.
