Firmware Overview 4.0

All SOMANET servo drives support cyclic synchronous modes of operation CSP, CSV, CST optimized for use in robotic applications. Firmware updates and storing of configuration files is possible via File over EtherCAT (FoE). Multiple concurrent encoders (for example BiSS, Hall) are supported.

An object dictionary according to CiA 402 is available, complemented with manufacturer specific objects to expand the feature set.

The following diagram depicts the basic architecture of the servo drive system:
