)
Note!
For a faultless homing with the REFC function block you have to deactivate the
touch probe function with PHINT5−TP−ENABLE = LOW during homing. (
3−263)
3.2.78.1 Select touch probe mode
l
C1186 = 0: terminal E4
– The input for the touch probe signal is terminal X5/E4. The signal refers to the function block
output MCTRL−PHI−ACT.
– The compensation function is activated immediately.
l
C1186 = 1: terminal E5
– The input for the touch probe signal is terminal X5/E5. The signal refers to the master angle
at X9 (DFIN function block).
– The compensation function is activated immediately.
l C1186 = 2: rotary knife
– The input for the touch probe signal is terminal X5/E5. The signal refers to the master angle
at X9 (DFIN function block).
– The compensation function is activated at zero crossing.
– Important: For this function, you have to connect the input PHINT5−DFIN to the output
DFIN−OUT.
– Select this mode for applications with a rotary cutter.
)
Note!
Save the settings with C0003 = 1 and switch the mains voltage off and on again.
l
When the mark synchronisation is parameterised, the function block
automatically changes to the "Modulo" or "Limited traversing range" mode. Only
by mains switching the touch probe function is initialised with the mode selected.
3.2.78.2 Evaluate touch probe signal edge
Via the input PHINT5−TP−EDGE−SELECT you can set the edge evaluation for the terminals X5/E4 and
X5/E5.
l PHINT5−TP−EDGE−SELECT = LOW
– Only the HIGH−LOW edges of the touch probe signal are evaluated.
l PHINT5−TP−EDGE−SELECT = HIGH
– Only the LOW−HIGH edges of the touch probe signal are evaluated.
