Product Description:

The CSB02.1B-ET-EC-NN-L3-NN-NN-NW is a drive controller manufactured by Bosch Rexroth Indramat for the CSB Drive Controllers series. The module supplies command processing, power regulation, and network connectivity for one servo axis in industrial automation lines. By translating Ethernet motion commands into finely timed current pulses, it helps keep conveyor speeds, pick-and-place arms, and indexing tables within specified position tolerances. This supports coordinated motion tasks that require stable response during changing load and speed conditions.

The controller is set up for a single mechanical loop because its axis count is 1, and it provides 11 digital inputs for discrete control signals. Fine analog reference values are captured with a resolution of 14-bit on the analog input channel, supporting proportional adjustments without noticeable quantization steps. Network traffic is exchanged over an industrial Ethernet layer that conforms to 100Base-TX, and the built-in Multi-Ethernet stack allows the same port to run EtherNet/IP, PROFINET, or SERCOS over IP without extra cards. Functional safety is implemented through STO (Safe Torque Off), which disables torque generation for emergency stop functions.

The extended interface includes 3 configurable slots that can accept encoder evaluation, I/O expansion, or fieldbus modules. Command voltages or diagnostic variables can be retransmitted through 2 analog outputs, while two probe inputs record latch positions for synchronization tasks. The Multi-Encoder Interface accepts EnDat, Hiperface, or TTL feedback and is presented beside an RJ-45, 8-Pin ET port that simplifies cable connection and replacement. When driving external contactors, the onboard relay can switch up to 30 V DC, preventing the need for a separate interface relay.
