Touch probe (TP)
A "Touch probe" (short: "TP") is an event which can for instance be actuated in an edge-controlled
manner via a digital input to detect an actual value (that changes quickly) at the time of activation
and to process it further within the program afterwards.
• Typical touch probe applications:
• Homing
• Mark synchronisation
• Measurements of lengths
• Up to 2 touch probe channels can be used in parallel for each axis.
• Possible touch probe sources:
• TP1 : Zero pulse position encoder or digital input DI1
• TP2 : Zero pulse position encoder or digital input DI2

Note!
The digital inputs DI1 and DI2 can be evaluated additionally as "normal" digital inputs
object any time (or
for axis B).
