After a learn run, the parameter "Maximum speed close" is set to 10 J and the parameter
"Nudging speed close" is set to 4 J based on the moved weight as determined during the learn
run.
Note
The actual kinetic energy occurring in the closing direction has to be checked during
commissioning, and the parameters "Maximum speed close" and "Nudging speed close" may
have to be adapted.
The maximum kinetic energy of the door is limited to 100 J. The maximum attainable door speed
is limited according to the dynamic mass determined during the learn run.
Calculation of the door speed (v) on the basis of the kinetic energy (W) and the dynamic mass
(m) determined during the learn run:
Speed limit curve (in the closing direction*)
The speed limit curve is the characteristic that determines the maximum permissible door speed
(closing speed), v
maximum kinetic energy of the door in the closing direction must not exceed 10 joules.
