7.2 Position detection (touch probe)
7.2.1 Function
The device enables the exact detection of current positions during the processing of commands. In the
process, the position detection function is triggered by the trigger signals at a trigger input (CAP
input). For this purpose, the corresponding input must be activated for the touch probe function. The
signal edge of the trigger event is parameterisable (edge). The typical internal signal runtimes of the
trigger signals are compensated by the firmware of the device. The positions can therefore be detec-
ted with high precision.
The source (Source ...) of the positions can be selected (e.g. primary encoder). The modulo limit val-
ues can be freely parameterised within the positioning range (+Mod/–Mod).
The touch probe function provides various modes
è
Tab. 398 Possible modes of the touch probe function. The position detection can take place once or
cyclically, for example. Within the modulo range, the range in which trigger signals shall be accepted
can also be limited (+LIM/–LIM).
The detected position and detection time are saved in one parameter each (X_out, T_out). The para-
meters can be evaluated during the record selection mode and read out through the device provide is
necessary.
