<If decelerating from a fixed output area>
The fixed output area (base frequency or higher) braking load is constant. Furthermore, the fixed torque area (less
than base frequency) braking load is proportional to the speed. Consequently, if decelerating (stopping) from the
fixed output area, calculate and add the discharge withstand current rating and permissible average loss for the
respective <If expressed with %ED for constant speed> and <If decelerating from a fixed output area> above.
 Discharging capability (F50)
The discharging capability refers to kWs allowance for a single braking cycle.
