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.

Inputs (VAR_IN)

window are suppressed.
