SINAMICS S120 Add-On Instructions

Function Description

The Drive control function blocks (AOIs) described in this section are intended to
provide SINAMICS S120 users help in engineering and integrating the S120 drives
into an automation system where a Logix family controller is the primary control.
The canned AOI's in this application guide have been designed to seamlessly
integrate in to the PROFIdrive telegram 1 and Siemens telegrams 102, 111, 352,
370 and 390 commonly used for controlling the S120 drive system.
It is possible to control a S120 drive as a simple speed controlled drive or a
positioning drive using the EPOS function enabled in the drive. The AOIs also
provide a quick implementation of basic drive control using the EtherNet/IP
communication interface. Using multiple instances of the AOI several S120 drives
axes can be controlled via the IO interface.

This telegram cannot be used with Servo Drive Objects. The 1st two words in and
out are the same as Telegram1. The advantage of T352 is that there are 4 Optional
User Defined Control Setpoints, and four added Status words returning to the PLC
for Current, Torque, Warning Word, and Fault Word.
