Product Description:

The CSB02.5B-ET-EC-EC-S4-NN-NN-NW drive controller is produced by Bosch Rexroth Indramat for the CSB Drive Controllers series. It serves as the control section that links an HMU power module to higher-level PLCs, supervising motion tasks in automated packaging, handling, and processing cells. By combining encoder feedback with a mix of digital and analog I/O, the unit delivers deterministic positioning while its integrated safety layer supports machine functions that need certified motion monitoring. This arrangement keeps motion control, signal processing, and axis supervision in one controller section rather than splitting those tasks across separate interface modules.

Hardware resources are arranged around a single motion channel that manages 1 axis. Command and diagnostic traffic move over Multi-Ethernet lines rated at 100Base-TX. For on-machine signaling, the input matrix provides 11 digital inputs, while the analog section adds 3 analog inputs for process variables and 2 analog outputs to feed reference values to external actuators. Two probe inputs capture time-critical edges, and dual multi-encoder interfaces maintain synchronized feedback. This mix allows the controller to react quickly to switches, sensors, and analog reference signals without requiring separate signal-conditioning hardware for routine machine functions.

Five configurable digital I/O points and 2 communication ports extend system interaction through an RJ-45, 8-pin connector that follows the IEEE 802.3 standard. Three optional slots accommodate fieldbus, memory, or additional feedback cards, and the onboard safety package is identified as Safe Motion, enabling safe torque-off, safe limited speed, and related functions without external relays. Encoder data, probe events, and calculated setpoints are forwarded to the compatible power section, designated HMU05, forming a compact axis module. The optional slots also give the controller room for application-specific expansion when the base configuration needs added communication or memory capability. Dual probe channels and dual multi-encoder ports support accurate position capture during inspection, printing, or cutting operations while Ethernet communication remains active.
