Activate touch probe evaluation
Via the input PHINT5−ENABLE−TP you can activate or inhibit the evaluation of the touch probe
signals.
l
PHINT5−ENABLE−TP = HIGH
– The touch probe signal is evaluated.
– The evaluated signal is output at PHINT5−TP−DIFF, PHINT5−TP−DIST and PHINT5−X−DIFF.
l
PHINT5−ENABLE−TP = LOW
– The touch probe signal is not evaluated.
– The output signals at PHINT5−TP−DIFF, PHINT5−TP−DIST and PHINT5−X−DIFF are not
updated. The signal evaluated last is output.
3.2.78.4
Compensation of a recognised deviation
If a touch probe signal arrives, the deviation between the current value of the integrator and the signal
is determined at PHINT5−TP−POS and is output at PHINT5−X−DIFF. In C1740 you can set the source
for the compensation speed.
l
C1740 = 0: code 1741/1
– Deviations that are recognised are compensated directly and immediately with the speed
defined in C1741/1.
– Value in C1741/1 = 0: no compensation of deviations.
– Via PHINT5−X−OFFSET you can apply an offset to the output signal at PHINT5−OUT.
l
C1740 = 1: input PHINT5−TP−SPEED−LIM
– Deviations that are recognised are compensated with the defined speed at
PHINT5−TP−SPEED−LIM.
– Signal at PHINT5−TP−SPEED−LIM = 0: no compensation of deviations.
– The input only is active if PHINT5−TP−SYNC−BUSY = High.
– The input signal solely takes effect on the integrator.
– Via PHINT5−X−OFFSET you can apply an offset to the output signal at PHINT5−OUT.

Note!
l
By separation of the functions "Measure the deviation" and "Compensate the
deviation", you can for instance measure material lengths.
l
The compensation process can be controlled by selecting a profile at
PHINT5−TP−SPEED−LIM.
l
The PHINT5 function block does not contain a profile generator. The profiles have
to be generated via additional function blocks (e.g. RFGPH2 or RFGPH3). See
also example in fig. 3−205.
– Do not specify constant values at PHINT5−TP−SPEED−LIM (e.g. via free codes
(FCODE)).
