10 Movement optimisation for the door
Adjusting the pre-limit switch positions and the ramps can optimize or improve the movement of
the door.
The following illustrations for OPEN and CLOSE moves show the operation of the frequency
converter.

Figure 44: Opening using frequency converter
The frequency converter starts the door movement with start ramp "r1". It accelerates from 0 Hz to
the max. travel speed.
The door is moved at the max. travel speed until the pre-limit switch for the limit position OPEN is
reached. At this point it reduces the speed of the door to creep speed using ramp "r2”. The door
now moves at creep speed until the limit switch OPEN is reached.
At this point the door is stopped (ro).
