Encoder As Drive Object - Siemens SINAMICS S120 Function Manual

Encoder as drive object

Overview
Encoders can be linked in as autonomous drive objects (Drive Object = DO) and evaluated. If
an encoder is integrated as a drive object, it can be addressed via PROFIBUS / PROFINET as
a stand-alone unit.
Requirement
● STARTER V4.1.5 or higher
● New or existing project with a CU320-2
Note
The project can also be created offline. Further information on this can be found in Section
"Commissioning" in the SINAMICS S120 Commissioning Manual with STARTER.
● Completely configured drive system
Function description
The function "Encoder as a drive object" is only available in the STARTER commissioning tool.
Using an "Encoder" drive object allows you to directly connect an encoder of an upstream
machine via a Sensor Module without having to take an indirect route via the 2nd encoder of a
drive. The encoder is connected via the encoder interface of a Sensor Module. If the Sensor
Module has its own DRIVE-CLiQ interface (e.g. a Sensor Module of the type SME20), then the
encoder can be connected to any free DRIVE-CLiQ socket.
Creating an "Encoder" drive object
The creation of an "Encoder" drive object is described using an example of a CU320-2. In this
example, the project is created offline using the STARTER commissioning tool.
In the project navigator, you can find the selection of the "Encoder" drive object between "Input/
output components" and "Drives".
