SEW DFE32B

SEW DFE32B

Product Introduction:
The DFE32B is a PROFINET IO fieldbus interface module designed by SEW-EURODRIVE for integration with MOVIDRIVE MDX61B and MOVITRAC B series drive converters. It serves as a communication gateway, enabling seamless data exchange between SEW drives and PROFINET-capable PLC systems such as Siemens S7-1200/1500. The module features an integrated Ethernet switch for line topology support and communicates with the drive via the internal S-Bus (CAN-based system bus). Configuration is performed through SEW’s MOVITOOLS MotionStudio software using GSDML files imported into the PLC engineering environment.

  • LED indicators for link status, activity, and bus communication status
  • Compact form factor suitable for control cabinet installation

Working Principle:
The DFE32B module acts as a protocol translator between the PROFINET IO network and the SEW drive’s internal S-Bus. When a PROFINET IO controller (PLC) sends a cyclic data frame containing control commands and speed setpoints, the DFE32B receives this data via its Ethernet interface, converts it into the S-Bus protocol format, and transmits it to the connected drive. Simultaneously, the module reads the drive’s operational status, current values, and diagnostic information via S-Bus, packages this data into PROFINET IO process data frames, and sends it back to the PLC. The integrated Ethernet switch allows multiple DFE32B modules or other PROFINET devices to be connected in a line topology, sharing a single Ethernet cable path.

Installation Requirements:

  • Install the module into a compatible expansion slot on the MOVIDRIVE MDX61B or MOVITRAC B drive
  • Connect the S-Bus cable (twisted pair) between the module and the drive’s S-Bus terminal
  • Connect Ethernet cables (CAT5e or higher) to the RJ45 ports for PROFINET network access
  • Set DIP switches appropriately: DEF IP=0 for DCP-based IP assignment, AS=1 for active S-Bus node
  • Terminate the S-Bus with the S1 DIP switch set to ON at the end of the bus line
  • Bridge X12 terminal 24V output to DI01 on the drive for enable signal
  • Ensure proper shielding and grounding of Ethernet cables per EMC guidelines

Usage Notes:

  • Import the SEW GSDML file into TIA Portal or the PLC engineering software before hardware configuration
  • Set the MOVITOOLS communication protocol to “MoviLink” instead of “CANbus” to avoid S-Bus errors
  • After successful S-Bus configuration, set DIP switch DEF IP=0 to prevent IP address reset after power cycling
  • Use MOVITOOLS MotionStudio for initial drive parameter configuration before PROFINET integration
  • Verify the “Communication OK” signal in the PLC program to confirm successful data exchange
  • The module is exclusively compatible with MDX61B and MOVITRAC B series; cross-series use with MC07B or other platforms will result in communication failure
