3.2.20.2 Homing
There are different possibilities of homing the drive:
l For commissioning, the reference is set once (reasonable for machines with risk of collision).
(
¶ 3−77)
l After mains connection, homing is carried out once, so that the drive finds the home position.
Possibilities for carrying out the homing process:
– Via the REFC function block (
¶ 3−261)
– Via the function "Set reference dynamically" (see below).
l Permanent mark registration during running operation (mark synchronisation):
– Synchronising via touch probe at terminal X5/E4. (
¶ 3−78)
– Synchronising via touch probe at CCTRL2−TPIN. (
¶ 3−79)
)
Note!
For a faultless homing with the REFC function block you have to deactivate the
touch probe function with CCTRL2−TPIN/E4 = LOW during homing. (

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 CCTRL2−N2−SET = HIGH
2. Define the position of the touch probe sensor on the machine at CCTRL2−TP−POS.
3. Set CCTRL2−TPIN/E4 = LOW.
4. A LOW−HIGH edge at CCTRL2−TPIN activates "Set reference dynamically".
B) If you activate the function via terminal X5/E4:
1. Set CCTRL2−N2−SET = HIGH
2. Define the position of the touch probe sensor on the machine at CCTRL2−TP−POS.
3. Set CCTRL2−TPIN/E4 = HIGH.
4. Select the signal edge for the input signal at terminal X5/E4:
– In the case of CCTRL2−TP−EDGE−SELECT = LOW, HIGH−LOW edges are evaluated.
– In the case of CCTRL2−TP−EDGE−SELECT = HIGH, LOW−HIGH edges are evaluated.
5. A corresponding signal edge at terminal X5/E4 activates "Set reference dynamically".
