8.14Camgroup(CAMswitch)
Two cam group outputs are implemented in ServoOne. Up to 4 tracks with max. 32
cam definitions can be assigned to each of the two outputs. This provides a
maximum of 128 configurable cams that can set or reset a digital output when
defined positions are reached. The performance characteristics of the cam group are
presented briefly below.

8.14.1Parametrizationofthecamgroup
The cam group implemented in ServoOne is realized analogously to a mechanical
cam roll with radially applied elevations (cams) along the roll axis. A maximum of up
to 128 cams can be arranged on the roll with start and end position in ascending
order in relation to the roller diameter. When the cam is reached, an output of the
controller can be switched.
The reference position for evaluating the electronic cam group can be selected
using parameter P 1427 MPRO_CAM_CamInPosFS.

The activation of a digital output via the cam group is done via the function selector
of the digital outputs. The function selectors of the digital outputs can be selected
using parameters P 122 - P 126 MPRO_OUTPUT_FS_OSDxx). Here the value
CAMLineA (45) - cam group track A or CAMLineB (46) - cam group track B must be
set.
