Function block L_SMC_TouchProbe (for EtherCAT)
Function library: L_SM3_DriveUtil.lib
This purpose of this block is to detect the position of the drive with a high degree of
accuracy via a fast input. Previously, the assignment and feedback of measured values
took place by means of SDO access. If the drive is controlled via an EtherCAT fieldbus, it
is possible to transfer these data as part of the cyclical process data. The advantage is
substantially faster transfer of the data from and to the drive. In order to be able to use
this, a corresponding mapping that contains these data as an item of process data
must be selected.
