- the output signal of the track (or the input signal of the control device) is therefore a position signal.
- a post with a speed profile not specified in more detail is lowered, while the other posts follow this position signal and thus have the same velocity profile.
- a damper is Darge ⁇ represents.
- the damper acts on a nut which, when lowered, causes a spindle to rotate.
- the spindle is connected to a geared motor.
- the gear motor can be used in the lowering as a brake for controlling the lowering movement.
