The following prerequesites are necessary to start the procedure:

  • Install ctrlX WORKS in its latest version (including ctrlX I/O Engineering).
  • Local Network with IPv4 in the same range as the ctrlX CORE
    • For connecting to the ctrlX CORE please check the network settings of your PC. The IP address needs to be in the same subnet, e.g. set IP configuration to manual, IP to "", subnet mask to "".
  • ESI File (EtherCAT Slave Information) for Synapticon drive needs to be downloaded (see below).

  13. Adding the Slave (Synapticon Drive).
    Connect the Synapticon Drive to the ctrlX CORE through the XF50 port physically, and power on the drive. Add the Slave by right-clicking on the Fieldbus and choosing the Scan Device option. The drives will appear on Control Side. Move them to Project Side with the buttons and press Apply. 

  14. Save the project.

  15. To see the real-time data from the slave and the PDO/SDO, select the slave on the Device (1) Menu, open the CoE tab (2), press Transfer Fieldbus Configuration (3), press Show Online Data (4), observe the Online status will appear (5), and select Description from slave (6). The list of the PDO/SDO will be loaded with the actual values.

The Company

Synapticon is reshaping the world of motion control for robotics and machinery at the point of motion. We are introducing an entirely new approach to motion axes by integrating formerly discrete components, such as servo drives, sensors, brakes and functional safety into seamless units to fit integrated motors and gearmotors. We are digitalizing performance and quality factors that are so far dependent on costly electromechanical and mechanical manufacturing. Together, these innovations disrupt the point of motion as we know it today, for good.
