User Manual of EM730 Series Inverter F04.20 : Set the starting frequency of DC braking in deceleration to stop. Once the output frequency is less than the set frequency during deceleration stop, and the time of DC braking for stop is not 0, DC braking for stop will be enabled. F04.21 : Set different values to apply the torques of DC braking for stop. F04.22 : Set the duration of DC braking for stop. If F04.22=0.00, DC braking for stop will be invalid. When an external terminal sends a signal of DC braking for stop, the duration of DC braking for stop will be larger of the valid time of the signal of DC braking for stop from the external terminal and the set time of F04.22. F04.23 :
When the output frequency reaches the set value of F04.20 during deceleration to stop, and the set time of F04.23 is up, DC braking will be enabled. The process of DC braking for stop is shown in Fig. 7- 18.
