Siemens SIDOOR ATD4 W Series - Adjustable Parameters; Driving Curve

5.9.4 Adjustable parameters
5.9.4.1 Driving curve
The optimum drive characteristics of the door are calculated and maintained continuously.
The driving curve transitions are rounded o󹪜 so that the door movement is smooth and jerk-free.

Reversal ramp close/open = Reversal of travel in direction "CLOSE" in direction "OPEN".
Reversal ramp open/close = Reversal of travel in direction "OPEN" in direction "CLOSE".
When reversing, the door is braked with the reversal ramp and starts the travel in the opposite
direction with the acceleration ramp.
