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

via the

0x60FD

object any time (or

0x68FD

for axis B).
