Product Description
Rexroth CSB02.1B‑ET‑EC‑NN‑S4‑DA‑NN‑FW is a single‑axis control section of IndraDrive Cs servo system. It must be combined with HCS02 power modules to form a complete servo drive system. Equipped with Multi‑Ethernet communication interface supporting major industrial Ethernet protocols. Multi‑encoder interface supports most common servo motor encoder types. DA digital‑analog I/O expansion is 
integrated. S4 enhanced Safe Motion safety functions including certified STO, SS1, SS2, SOS are implemented. On‑board drive‑based PLC complies with IEC61131‑3 for motion & logic programming. Commissioning via IndraWorks software; optional operator panel and expansion slots available. Compact book‑style design for cabinet mounting with IP20 protection. This model is manufacturer discontinued; only surplus, used‑tested and refurbished spare parts available on marketIndramat U….
