Product Description:

The CSH02.1B-CC-EC-ET-S4-EC-NN-FW is an advanced motion and communication controller built by Bosch Rexroth Indramat for the CSH Advanced Controllers series. Installed beside IndraDrive power sections, it supervises multiple axes, processes field signals, and bridges plant networks to the drive bus. Within an automated cell it translates higher-level commands into synchronized position and torque references, while also monitoring safety inputs and encoder feedback to maintain deterministic machine operation.

This controller handles differential analog signals within a ±10 V window, and its conversion circuitry resolves those values to 14-bit precision, allowing fine set-point or feedback scaling without external converters. Internal electronics draw only 17 W at idle, minimizing cabinet thermal load, yet the digital output stage can source up to 500 mA per channel for valve coils or indicator lamps. When EtherCAT is selected as the real-time bus, inbound telegrams enter through port X25 P1; outbound frames are forwarded on X24 P2 to form a daisy chain. Start-up surge is limited to <5 A, so standard 24 V supply breakers are sufficient even during cold-start charging of filter capacitors.

The logic section is powered from a DC 24 V feed and integrates certified Safe Motion functions, so motion can be stopped or limited by hardware channels without shutting off the main drive. Its built-in Multi-Ethernet interface supports sercos III, EtherCAT, EtherNet/IP, and PROFINET IO; this flexibility is summarized as Multi-Ethernet and lets the same hardware fit diverse plant standards. Two high-speed encoder ports accept EnDat or Hiperface signals, while resolver transducers are not supported, steering designers toward fully digital feedback loops. A relay rated for 1000 mA is present for auxiliary load shedding, and the fieldbus master capability on sercos III coordinates subordinate drives directly so additional PLC slots are not required.
