Speed limit curve (in opening and closing direction)
The speed limit curve is the characteristic that determines the maximum permissible door speed
(closing speed), v
max
, as a function of the total door panel weight. According to machine
protection guideline EN ISO 14120:2015, the maximum kinetic energy of the door in the closing
direction must not exceed 10 joules.
