Product Description:

The CSB02.1B-ET-EC-CN-S4-EM-NN-FW is a drive controller manufactured by Bosch Rexroth Indramat for the CSB Drive Controllers series. It couples servo axes to Ethernet and CAN networks, interprets encoder feedback, and manages integrated safety logic, giving automated lines deterministic motion control and fault-tolerant shutdown capability in compact control cabinets. The control section combines communication, feedback handling, and axis supervision in one unit, which supports coordinated motion in packaging, assembly, and material-handling systems.

This controller runs from a logic supply of DC 24 V and draws only 17 W, minimizing the load on common low-voltage power rails. Multi-Ethernet hardware exposes 2 Ethernet ports that communicate with upper-level PLCs over 100Base-TX, and the sockets are arranged for simple daisy-chain topology with standard RJ-45 cabling. For machine signals, it provides 11 digital inputs plus five configurable lines that can act as inputs or outputs, allowing the same unit to handle sensors, interlocks, or handshake tasks. Functional safety is handled internally through Safe Motion technology, so emergency-stop, safe-stop, and speed-monitoring functions execute without external relays.

The multi-encoder interface can output absolute position in SSI format and also supplies absolute and incremental encoder emulation, so legacy controllers receive the same position data used by the drive. Two probe inputs capture precise registration edges, while 2 ±10 V analog outputs can feed oscilloscopes, torque monitors, or external regulators. A built-in CANopen fieldbus node supports low-bandwidth diagnostics when Ethernet is reserved for motion. The combination of encoder processing, probe capture, and analog monitoring allows the controller to support synchronized axes that require accurate registration and continuous status visibility.
