Touch probe configuration
The touch probe channel for positioning with touch probe detection can be selected in the »Engi-
neer« via the parameter dialog of the FB L_PositionerTable.
• Go to the parameter dialog of the FB L_PositionerTable and press the Setting up touch probe
button to open the Setting up touch probe dialog box and select the desired setting for the cor-
responding profile.
• The setting selected in this parameterisation dialog has a direct effect on the setting of C04721/
1...75 ("touch probe configuration") and vice versa.
• For a direct setting of C04721/1...75 (e.g. via keypad) the following table lists the corresponding
decimal values for all possible configurations.
• Example: For the selection of the touch probe channel "DIGIN 8" and the response to only one
positive edge, the decimal value "16384" must be set in C04721.
5.111.6 Monitoring for counter overflow
This function extension will be available from library V2.02!
If the machine parameters transferred to the FB via the AxisData input are changed afterwards (e.g.
the gearbox factors), this may cause a counter overflow when the speed, acceleration, and position
values defined via parameters are converted from the real unit to the internal unit.
The FB causes a corresponding error message in case of an internal counter overflow due to a chan-
ged measuring system:
