Product Description:

The CSH02.5B-ET-EC-EC-S4-NN-NN-FW controller is manufactured by Bosch Rexroth Indramat for the CSH Advanced Controllers series. It serves as the primary intelligence for servo drives, managing motion profiles, encoder feedback, and machine safety inside automated production equipment. By integrating communication interfaces and local I/O, the unit links higher-level PLCs to the power electronics that energize motors, enabling precise position, velocity, and torque control across diverse industrial processes.

Motion processing is centered on a single servo channel, and the controller is designed for 1 axis while supervising position loops through two identical Multi-Encoder ports. Each port can supply feedback devices with either 12 VDC or 5 VDC, and both voltage rails have separate current limits of 500 mA for resolvers, TTL devices, or absolute encoders without external power supplies. Field signals enter through 11 digital inputs, three analog inputs, and five configurable digital lines that can be assigned as outputs for marker pulses or general machine functions. Safety is integrated through the Safe Motion package, which supports monitored velocity, standstill, and shutdown functions directly inside the controller.

For cabinet integration, the backplane provides 3 optional slots that can be used for technology modules such as additional fieldbus couplers or memory cards. Real-time plant connectivity is handled by the built-in Multi-Ethernet interface, which supports synchronized cyclic data exchange with EtherNet/IP, PROFINET, or EtherCAT hosts without extra hardware. The controller connects electrically with the HMU05 power section, forming a compact drive stack in which the logic section governs the current and voltage loops generated by the inverter stage. Two probe inputs capture edge-triggered position events for measurement tasks, while the pair of 2 analog outputs can transmit speed or torque setpoints to external actuators or provide operating values for diagnostics.
