6.4 Touch probe detection
This function extension is available from version 06.00.00!
"Touch probe" (TP) in general means quick detection of a position by a quick sensor if the
pulse duration of the sensor signal is too short to be detected by a "normal" digital input
(scanning time: 1 ms).
Moreover, touch probe requires exact detection of the position. Here, the difference in
position between the 1 ms position detection and the touch probe signal is considered as
correction value.
Applications:
 Precise approach of a position at a previously detected signal mark
 High-precision traversing of a section starting at a previously detected signal mark
 Safe detection of signal marks with very short signal edges
 Measurement of a high-precision position at a previously detected signal mark
 Homing to touch probe (homing signal)
 Relative residual path positioning (traversing of a section starting at signal mark)
 Absolute positioning to target position, activated by a safely detected signal mark
 Position measurement of a distance between 2 signal marks
