Factory setting: 0.00
Settings 0.00~120.00Hz
During the period AC motor drive decelerating to stop, this parameter sets the DC brake starting
frequency If Pr.05-24 is lower than Pr.01-09 (starting frequency), DC brake will regards lowest frequency
as starting frequency.

During the door close, it will re-close from the open complete position to the close complete position
when there is an obstacle (the stall current exceeds Pr. 05.25/05.26/05.28/05.29). Door close command
will be ignored when the drive is perform re-opening and will be valid again after door completely open is
reached.
Pr.05-33 sets the time for decelerating to 0 Hz when door close error occurs. It is recommended to set a
minimum value less than the current limit in order for door to re-open in shortest time to ensure
passenger’s safety.
