The touch probe is used if the zero pulse (zero position of the position encoder) does not
occur reproducibly at the same position due to the mechanical structure. It is also possible
that the zero pulse is mechanically shifted after a motor replacement.
The load (e.g. slide) travels from its original position beyond the reference switch to the
first touch probe signal after leaving the reference switch. This touch probe signal bears
the home position. A HIGH level is pending at the digital input X6/DI2. Before homing, the
load may already be situated on the reference switch.
Use X6/DO1 to switch a relay which changes over between reference switch and touch
probe sensor at X6/DI2. (
