Integrating the inverter via an AS-Interface master from Siemens

The following device topology is used in the example:

  • Higher-level controller (PLC) SIMATIC S7
  • AS-Interface master from Siemens CM_AS-Master ST/ET200SP (3RK7 137-6SA00-0BC1)
  • MOVIMOT® flexible MMF1../DAC.. decentralized inverter

The following figure shows the basic device topology:

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

  • MOVISUITE® for inverters from SEW‑EURODRIVE
  • TIA Portal (SIMATIC STEP 7) from Siemens for the PLC and the AS‑Interface master

The drive unit is integrated into the network in several process steps:
