Cam track features
A cam track has parameters that are valid for the track as a whole, and parameters that can
be configured for each single output cam on a track.
Track data
Track data is valid for all output cams on a track and is, therefore, configured for the cam track
as a whole.
● Output cam type
Position-based, time-based, etc.
● Cam track start
Always defined from "0"
● Track length
Cam track start to cam track end
● Hysteresis
Even if the switching conditions change, the output cam does not change its switching state
in this defined range around the switching position.
● Actuation times
Actuation times can be specified to compensate for the switching times of digital outputs
and connected switching elements.
● Axis reference position
Cam tracks are defined independently of the axis. The axis reference position is used to
define how the cam track is mapped on the axis, or from which axis position the cam track
should be output.
● Cyclic or non-cyclic activation mode
If the cam track is output non-cyclically, it will have to be reactivated after execution.
● Start mode and stop mode
Start mode or stop mode can be used, for example, to define whether a cam track will be
output immediately or not until the next track cycle.
Output cam data
Output cam data can be configured separately for each single output cam on a cam track.
● Output cam parameters:
Depending on output cam type, start position, end position, ON duration, maximum ON
length.
● Validity of single output cam
Single output cams on a defined cam track can be parameterized as "invalid." This output
cam is completely suppressed and is not output. It also has no status indication.
