Product Description:

The CSB02.1B-ET-EC-CN-NN-EC-NN-FW is a compact drive controller produced by Bosch Rexroth Indramat within the CSB Drive Controllers series. It provides axis control, fieldbus connectivity, and local input and output handling for servo-based machinery such as packaging stations, pick-and-place gantries, and material-handling cells. It coordinates motor power stages and exchanges real-time data with higher-level PLCs, supporting synchronized motion and diagnostic feedback in industrial automation.

In operation, the controller handles 11 digital inputs for limit switches or sensor states, while 5 configurable I/O points can be set as either inputs or outputs depending on machine logic. Three analog inputs allow process variables such as tension or temperature to be read, and the unit supplies two analog outputs for proportional valve or speed reference signals. Two probe inputs provide latch functions for high-speed position capture, and the dual Multi-Encoder interface accepts feedback from incremental or absolute encoders. Network traffic passes through an 8-pin RJ-45 port that follows the 100Base-TX Ethernet standard, enabling Multi-Ethernet communication to servo drives, PLCs, or diagnostic computers without a protocol change.

The switching section sources up to 500 mA on each digital output, allowing direct actuation of indicator lamps or solid-state relays. For heavier loads, the internal relay path is rated at 1000 mA and can switch up to 30 V, isolating field wiring from the logic domain. Overall power draw remains at 19.6 W, which helps keep cabinet heat generation low. When a distributed architecture is preferred, the controller also supports the CANopen fieldbus through a D-Sub 9-pin connector, allowing up to 127 nodes on the same network while maintaining deterministic control channels alongside the Ethernet backbone.
