Cam track parameters

4.2.3.1 Track length
The camTrackLength system variable is used to parameterize the track length. The track length
is calculated from the start of the cam track (always 0) to the end of the cam track. Usually,
the output cams of the cam track are located within the track length. The track length must not
be 0. When track length = 0, an error is reported when the cam track of a non-modulo axis is
activated. If track length = 0 for a modulo axis during cam track activation, the cam track length
is set to the axis modulo length.
4.2.3.2 Effective direction and behavior
The following diagram shows output cam behavior on switching on and off, without hysteresis,
activation or deactivation time.
Figure 4-9
The switching characteristic depends only on the position (position setpoint or actual position).
The cams on a cam track switch independently of the direction of motion, i.e. they always have
