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
Machinery Directive EN953, the maximum kinetic energy of the door in the closing direction
must not exceed 10 joules.

Example from the following speed limit curve:
● Moved mass m = 180 kg => v
Figure 3-3
If the reversing device is switched off, the maximum kinetic energy must not exceed 4 joules.

Speed limit curve for WKIN=10J
= 1/2 m ∙ v² = 4 J.
= 0.33 m / s.
