4.2 TO Cam Track basics
4.2.1 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
● Cam track start
● Track length
● Hysteresis
● Actuation times
● Axis reference position
● Cyclic or non-cyclic activation mode
● Start mode and stop mode
Output cam data
Output cam data can be configured separately for each single output cam on a cam track.
● Output cam parameters:
● Validity of single output cam
66
Position-based, time-based, etc.
Always defined from "0"
Cam track start to cam track end
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 can be specified to compensate for the switching times of digital outputs
and connected switching elements.
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.
If the cam track is output non-cyclically, it will have to be reactivated after execution.
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.
Depending on output cam type, start position, end position, ON duration, maximum ON
length.
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.
