Integrating the inverter into an EtherCAT® network

The following device topology is used in the example:

  • Higher-level controller (PLC) CX2020 from Beckhoff Automation GmbH with EtherCAT® extension EK1110
  • MOVIDRIVE® modular application inverter, MDD90A double-axis module (CiA402: MDDA90ACiA402)
  • MOVIDRIVE® modular application inverter, MDA90A single-axis module with MOVISAFE® CSS21A safety card (CiA402: MDA90ACiA402)

The following figure is a schematic representation of the device topology:

For configuration and startup of the devices, the following tools are used:

  • TwinCAT 3 from Beckhoff Automation GmbH for the PLC
  • MOVISUITE® for inverters from SEW‑EURODRIVE

The inverter must be created in the I/O configuration of the EtherCAT® master.
