5.5 Configuring isochronous mode for a Motion Control application
Introduction
The configuring of isochronous mode for a Motion Control application with cam output is
described in the following.
You connect a SINAMICS V90 drive with a positioning axis to an S7-1500 CPU as
isochronous distributed I/O.
The drive is controlled using the CPU-internal Motion Control functions.
You connect the cam output to the CPU as an isochronous cam output using technology
module TM Timer DIDQ 16 x 24V.
Requirements
● The network view of STEP 7 is open.
● An S7-1500 CPU has been placed (e.g. CPU 1516-3 PN/DP).
Procedure for configuring isochronous mode for a drive
For isochronous operation of a drive, you configure the drive frame as an isochronous frame.
So that the CPU can control the drive, you then assign the drive to a Motion Control
technology object of the CPU.
Follow these configuration steps:
1. Insert a SINAMICS V90 drive from the hardware catalog in the network view (Additional
Field Devices > PROFINET IO > Drives > SIEMENS AG > SINAMICS > SINAMICS V90
PN).
2. Connect the PROFINET interface of the V90 to the PROFINET interface X1 of the CPU in
the network view.
3. Change to the topology view. Interconnect the corresponding ports of the PROFINET
interfaces of the devices.
4. Select the V90 and change to the device view.
5. In the properties of the V90, navigate via General > PROFINET interface > Advanced
options to the "Isochronous mode" area.
6. Select the "Isochronous mode" option.
