maximum of 64 cam limit positions are possible.

8.14.1.3 Hysteresis value for all cams of a track
To avoid jitter effects, a hysteresis value can be specified for all cams of a track. This
is configured using P 1422 MPRO_CAM_CamHystConf. The hysteresis value can
be set individually for each track.
The hysteresis is specified in user units. The value 0 means that no hysteresis is
effective on this track.

If a value of >0 is entered for the hysteresis, hysteresis is automatically activated for
all cams on this track. The first time the cam passes through the cam limit, it is
switched at the original position C. As long as the position then remains in the range
A-E, any further switching off and switching on takes place at the defined hysteresis
positions B and D, i.e. switching off at position B, switching on at position D. Only
when the current position exceeds limit E or is moved to before A again, will the
output once again be switched at the original position C.
The specification of the hysteresis has an effect on the minimum cam length and the
minimum cam spacing. The minimum cam length and minimum cam spacing are
given by the formula:

8.14.1.4 Masking of individual cams
Individual cams can be masked out on each cam track. These are then hidden and
have no effect on the switching of the outputs.
This is set using P 1423 MPRO_CAM_CamMaskConf. The parameter values are
binary coded. Each bit stands for one cam. A 1 means that this cam is active. A 0
means that this cam is hidden. By default, all cams are active.
