7.7.8.4 Cam Switch Function
MC_DigitalCamSwitch
Specify the tappet position. True when the moving axis reaches the specified position, then turn to False when
passing it. The following example regards to configuration settings.

Example: Use two switches in the same track with MC_DigitalCamSwitch instruction.

Parameter setting
Parameter Type Switch1 Switch2
TrackNumber INT 1 1
FirstOnPosition [u] REAL 200 400
LastOnPosition [u] REAL 300 -
AxisDirection INT 0=Both 0=Both
CamSwitchMode INT 0=Position 1=TIME
Duration TIME - 2500ms

Trigger and timing
-
Switch 1 on Track 1 is ON when the position reaches 200 and turns to OFF once the axis position reaches 300.
-
When the position reaches 400, Switch 1 turns to ON again for 2500ms and then shifts to OFF.
7.7.8.5 Position Capture
MC_TorchProbe captures and records an axis position when a trigger event occurs.
A total of two trigger signals can be configures for each axis. MC_AbortTrigger is used to abort capture function.
Function description:
-
The touch probe operation activates for only one time for recording the very first trigger signal after Execute is
set as True. When a valid position is captured and recorded, the following trigger signals will be ignored.
-
One function block instance should relate to only one MC_TouchProbe instruction.
-
If there were multiple function block instances on the same capture and axis, the members of
MC_TRIGGER_REF should be added with TouchProbeID, which identifies different TouchProbe actions. The
definition of TouchProbeID can be associated to MC_AbortTrigger.
-
The operation of MC_TouhcProbe with window mask function is demonstrated as below:
