3.2.78 Phase integrator (PHINT5)

3−252

EDSVS9332K−EXT EN 4.0

3.2.78.3 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)).
