Oscillation protection
The oscillation protection prevents permanent oscillation of the door at the end stop.
End position "open"
If the system is pressed out of the end position with the drive order "open" present, the
system detects that the "open" position has been left, and attempts to return to the end stop
with the set static opening force.
After reaching the end stop, the drive is pressed against the end stop with the set continuous
torque.
The behavior described may be repeated five times (oscillation). After the fifth repetition, the
oscillation is interrupted by an idle time. The set continuous torque is effective during this
time. After expiry of the idle time, the system responds to corresponding oscillations again.
The duration of the idle time is between 10 and 30 s and depends on the overload state of
the controller and/or motor. See also Section Overload protection (Page 29).
End position "closed"
If the system is pressed out of the end position with the drive order "close" present, the
system detects that the "closed" position has been left, and attempts to return to the end
stop with the set static cutter force.
After reaching the end stop, the drive is pressed against the end stop with the set cutter
press-on torque. After 2 s, the cutter press-on torque is limited to the set continuous torque.
The behavior described may be repeated five times (oscillation). After the fifth repetition, the
oscillation is interrupted by an idle time. The set continuous torque is effective during this
time. After expiry of the idle time, the system responds to corresponding oscillations again.
The duration of the idle time is between 10 and 30 s and depends on the overload state of
the controller and/or motor. See also Section Overload protection (Page 29).
