Product Description:
The CSH02.1B-CC-EC-ET-S5-NN-NN-FW is a control section in the CSH Advanced Controllers series from Bosch Rexroth Indramat. Installed on an IndraDrive power module, it governs servo axes, interprets feedback, and forwards synchronized commands to support decentralized machine control. By combining master communication, axis calculation, and certified safety in a single board, the unit supports packaging, printing, and handling equipment that require coordinated multi-axis positioning and precise speed regulation.
Its network backbone is a Sercos III master channel that issues deterministic telegrams to connected drives. The logic electronics operate from a stabilized 24 V DC control supply, and an inrush limiter keeps switch-on demand below 5 A for only 1 ms. Compliance with IEEE 802.3 allows direct connection to standard industrial Ethernet infrastructure. Device configuration and service data travel through an EC D-Sub 15-pin female connector, while incremental, absolute, and serial feedback sources attach to the multi-encoder interface. This variant does not accept resolver signals, and the built-in relay path is rated for 1000 mA of continuous load.
Supplementary Ethernet traffic is managed by the ET expansion, which draws 2.7 W from the backplane and is wired through the X22 P2 / X23 P1 port pair. It can handle Sercos III, EtherCAT, EtherNet/IP, and PROFINET IO without additional hardware, letting one controller bridge mixed fieldbus zones. Functional safety is implemented with S5 Safe Motion, and its protected outputs can source up to 350 mA for external enable chains. The safety electronics require 2.5 W, and real-time redundancy is provided on the Sercos III port pair X24 P2 / X25 P1 to keep axis communication active if a cable is damaged.
