Speed Limit Cycle - Siemens AT18 Operating Instructions Manual

12 Speed limit cycle

The speed limit cycle is the characteristic for the determination of the maximum acceptable door
speed Vmax, depending on the total door panel weight. According to EN 81 the maximum kinetic
energy of the door in the closing direction may not exceed 10 joules. W
Example from the following speed limit cycle:
Total door panel weight m = 180 kg => V

NOTICE
The speed can be set in the range between 0 % and 100 %. The 0 % value represents a speed of
0.10 m/s.
The 100 % value represents 0.5 m/s at motor  (4V/1.8A, up to 10kg door weight) and 0.65 m/s
at motor 3 (30V/4A), up to 180 kg door weight)
= 0,33 m/s.
