Product Description:
The CSB02.1B-ET-EC-NN-SB-NN-NN-AW is a compact drive controller manufactured by Bosch Rexroth Indramat for the CSB Drive Controllers series. It provides closed-loop axis regulation for industrial automation cells by coordinating motor feedback with command data from supervisory PLCs. By combining power regulation, encoder evaluation, and field network connectivity in a single module, the device reduces panel complexity in multi-axis machinery. Its integrated layout also helps keep control functions centralized instead of spreading them across several separate interface modules.
The control core dissipates only 17 W of base power, leaving thermal headroom for option cards that can be installed in three available slots. Command exchange occurs over the built-in Multi-Ethernet interface, and the unit also provides 11 dedicated digital input channels for fast local sensor signals. Motion programs can issue 2 differential analog outputs for velocity or torque reference tasks. Discrete actuators such as brakes or couplers are supplied through a sink-capable terminal that delivers up to 500 mA of digital output current. The Multi-Encoder Interface accepts EnDat, Hiperface, or resolver feedback formats, which allows the controller to work with several common motor feedback systems. Separate internal power reserves are also provided for Ethernet expansion and the Safe Motion Bus safety function.
Fine positioning is supported by an analog output resolution of 24 mV/incr, which helps the controller send smooth reference changes to connected devices. The unit also has 5 configurable I/O terminals, allowing flexible assignment of limit switches, ready signals, or other local control functions without added relay hardware. Network traffic is carried on a shielded RJ-45, 8-pin connector operating at 100Base-TX speed, and diagnostics are forwarded through the same connection. Three optional slots allow the controller to add incremental encoder processing, extra fieldbus capability, or battery-backed safety cards as application needs change.
