Configuration - Encoder

The external encoder records the position of an externally controlled drive. The encoder
required for this purpose communicates the encoder position to the controller by means of a
PROFIdrive frame. In the "Encoder" configuration window, configure the encoder coupling
with which the encoder is to be connected.
Select encoder coupling:
In this area, select how the encoder will be connected in keeping with the graphic
representation.
● Connection via technology module (TM)
Select this option, if the encoder is connected to a technology module (TM).
– Technology module:
● Connection via PROFINET/PROFIBUS (PROFIdrive)
Select this option, if you are deploying a PROFIdrive compatible encoder.

In the "Technology module" field, select a technology module that has already been
configured, and the channel to be used. Only technology modules set to the "Position
detection for motion control" mode are displayed for selection.
If no technology module is available for selection, change to the device configuration
and add a technology module. If you have selected a technology module, you can
change to the configuration of the technology module using the "Device configuration"
button.
You can operate the technology module centrally on an S7-1500 PLC, or distributed
on a distributed I/O. You can identify the technology modules suitable for position
detection for Motion Control in the documentation for the technology module and the
catalog data.
– Encoder:
In the "Encoder" field, select a configured encoder on PROFINET/PROFIBUS. If an
encoder was selected, then it can be configured using the "Device configuration"
button.
Switch to the device configuration in the network view, and add an encoder, in the
event that no encoder can be selected.
