Product Description:
The CSH02.1B-ET-EC-EM-L3-NN-NN-FW advanced motion controller is supplied by Bosch Rexroth Indramat and belongs to the CSH Advanced Controllers series. In multi-axis drive systems, this module coordinates servo loops, fieldbus traffic, and safety inputs, acting as the central processing element between higher-level PLCs and inverters. It combines communication handling and feedback processing in one housing, which helps reduce the number of separate control components inside the drive system. It is suited to applications where multiple axes must exchange timing, position, and status data with low latency. By merging real-time Ethernet channels with encoder evaluation circuits, the CSH02.1B-ET-EC-EM-L3-NN-NN-FW supports synchronized motion in packaging, printing, and material-handling lines.
During operation, the controller draws a base power of 17 W, so heat dissipation inside the cabinet remains low. Its logic and peripheral circuits are energized from a DC 24 V supply, allowing direct connection to standard machine power buses used in industrial equipment. Network traffic moves through a 100Base-TX physical layer and can travel up to 100 m over Cat5e cabling before signal regeneration is required. Multi-Ethernet communication supports deterministic messaging over SERCOS III, EtherCAT, EtherNet/IP, and PROFINET IO for flexible plant integration. The combination of low power draw and a standard supply voltage simplifies cabinet integration in distributed automation layouts.
Feedback handling is supported through the EM option card, where RS-422 encoder streams are accepted at frequencies of up to 4 MHz and shielded lines can extend to 40 m without additional amplifiers. Safe drive disable is implemented with the STO function; its IEC 61131-2 inputs switch off torque internally, and connected source drivers may switch up to 350 mA without added relays on many axes. A 15-pin D-Sub socket is provided for motor encoder wiring, and dual RJ-45 ports simplify daisy-chain layouts. This arrangement supports compact machines that still require high-speed position sampling.
