When reversing from the open to the close direction, the door is braked with the reversing ramp OPEN_CLOSE, and starts
the closing movement with the acceleration ramp CLOSE.
WARNING
After the elevator door has been commissioned, the energies and forces on the heaviest door in the entire elevator system
must be checked by the service personnel, and adjusted if they exceed their limiting values.
The speed limit curve is the characteristic curve which defines the maximum permissible door speed Vmax as a function of
the total door panel weight. According to EN 81, the maximum kinetic energy of the door in the closing direction must not
exceed 10 joules.
If the reversing device is switched off, the maximum kinetic energy must not exceed 4 joules.
Gearing up or down is not allowed on the toothed belts because this would change the kinetic energies or static forces on
the door.
The door width is then no longer valid.
