SOMANET Servo Node EtherCAT

Our EtherCAT Servo Drive application features cutting-edge functionalities such as CSP, CSV, CST. Updating firmware and storing files is possible over EtherCAT (FoE). Multiple concurrent encoders (for example BiSS, Hall, SSI) are supported.


The following block diagram depicts the entire schematics of the EtherCAT Servo Drive system:


Functionality description

  • Storing files via FoE
  • Encoders support: BiSS-C, SSI, Hall, QEI, I2C, SPI
  • Multiple concurrent encoders support
  • Simple commissioning and tuning with OBLAC Drives

Getting started

Initially you will set up and plug in your SOMANET Servo Node.

STEP 1: Set up your SOMANET Servo Node

After setting up your system you need to install the latest Firmware and your motor needs to be tuned, so that the closed-loop controller works perfectly. Our OBLAC Drives application guides you through the firmware installation, commisioning and tuning process.

STEP 2: Install and run OBLAC Drives

Each system needs a master software that commands the slaves, OBLAC Drives already incorporates the IgH Master for Linux which runs also on a virtual machine under Windows. Please refer to the documenation of EtherLab for more information about IgH Master for Linux

For running your master application on a Windows system please refer to Beckhoff’s TwinCAT documentation.

Operating your Servo Node

Refer to our comprehensive Operation Manual that will help you run your motors up to an entire motion control system.
