Output activation mode

Cam tracks can be output in a cyclic or non-cyclic mode. This setting is also transferred when
activating the cam tracks (_enableCamTrack)
Cyclic output
The CYCLIC setting in the activationMode parameter is used to predefine the activation mode
for cyclic output of the cam track.
The cam track's track length is mapped from the start position and continued/repeated
cyclically. The cam track switches after the axis reference position and remains active until it
is switched off with _disableCamTrack.
Non-cyclic output
The NO_CYCLIC setting in the activationMode parameter is used to predefine the activation
mode for non-cyclic output of the cam track.
The cam track is mapped from the start position, output once only and terminated automatically
after reaching the end position or remains active in the axis range. The performance depends
on the value of the configuration date octBaseCfg. keepEnabledOutOfTrackRange.
Example of cyclic and non-cyclic output
A cam track is mapped onto a modulo axis. The figure shows a representation of the different
activation modes.

4.2.3.10 Axis reference position and cam track offset
Cam tracks are defined independently of the axis. Output cams are not calculated according
to the defaults until they are mapped onto the axis. The
(enableCamTrack.axisReferencePosition) axis reference position is used to define from which

Description
Track is deactivated at its end. Immediately the final output cam on the track switches,
the track is deactivated. Up to that point, a time-based cam on the track is output.
The last programmed start mode is active. If a start mode is not programmed, the user
default setting is used.
