Setting the reference dynamically
This function for instance can be used to traverse to the mark in the inching mode.
A) If you activate the function via the input CCTRL2−TPIN:
1. Set CCTRL−N2−SET = HIGH
2. Define the position of the touch probe sensor on the machine at CCTRL−TP−POS.
3. Set CCTRL−TPIN/E4 = LOW.
4. A LOW−HIGH edge at CCTRL−TPIN activates "Set reference".
B) If you activate the function via terminal X5/E4:
1. Set CCTRL−N2−SET = HIGH
2. Define the position of the touch probe sensor on the machine at CCTRL−TP−POS.
3. Set CCTRL−TPIN/E4 = HIGH.
4. A HIGH−LOW edge at terminal X5/E4 activates "Set reference".
Synchronisation via touch probe at terminal X5/E4 1
A touch probe signal at terminal X5/E4 is the quickest and most accurate mark registration and is
suited for a cyclic synchronisation.
Application examples:
l For applications without a homing function.
l After mains connection, the measuring system of the controller and that of the machine can
diverge very much. In the majority of cases the path to be compensated is very long.
l For applications (e. g. with conveying belts) an occurring slip has to be compensated by cyclic
synchronisation. In the majority of cases the path to be compensated is relatively short.
Procedure:
1. Set CCTRL−TPIN/E4 = HIGH.
2. Define the position of the touch probe sensor on the machine at CCTRL−TP−POS.
3. Activate the compensation limitation with C1366 = 1.
4. Enter the value for the maximum compensation speed in C1365/1 (Lenze setting = 100 rpm).
5. A HIGH−LOW edge at terminal X5/E4 synchronises the drive to the set position which is output
at CCTRL−PHI−SET.

Note!
l For applications with feed the final Y value of the profile must be assigned to the
input CCTRL−Y−END (e.g. by the output CDATA−Y−END). The function is not
suitable for stretching and compression.
l The input CCTRL−SUB−Y−END must be linked with the output CDATA−X0.
l Save the settings with C0003 = 1 and switch the mains voltage off and on again.
– 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.
