BAUMÜLLER BM4-F-IEE-01
The BM4-F-IEE-01 module acts as a distributed I/O node on the EtherCAT network. The BM4 servo drive (master) cyclically reads digital/analog input states and writes digital/analog output states via the EtherCAT protocol. Each EtherCAT frame processes all I/O data within a single network cycle (125 µs to 1 ms depending on configuration). The module's internal microcontroller handles signal conditioning, A/D and D/A conversion, and galvanic isolation, providing the servo drive with real-time field data for motion control logic and safety functions.
