4 - 18
Re-open Acceleration Boundary
Unit: 0.1
Settings 8.0 to 97.0% (100% is the door width,
acceleration area is Pr. 4-18~100%)
Factory Setting: 70.0
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.4-10/4-11/4-12/4-13).
Pr.4-14 is used to set the time for decelerating to 0Hz when there is an obstacle. It is
recommended to set a minimum value that less than the current limit to re-open in the shortest
time for people’s safety.
It needs large current when accelerating for start open/close door. Therefore, it needs to have
larger re-open current in the acceleration area. Please refer to following figure for setting re-
open current and acceleration area.
