Product Description:

The CSB02.1B-ET-EC-EP-S4-NN-NN-AW is a single-axis drive controller built by Bosch Rexroth Indramat for the CSB Drive Controllers series. The device supplies closed-loop control to synchronous and asynchronous motors and integrates into automation cells through its Multi-Ethernet communication layer. By combining power electronics, machine safety, and motion logic in one compact housing, the unit coordinates speed, position, and torque commands between higher-level PLCs and connected actuators. This layout supports coordinated machine operation where motion commands, status handling, and protective functions must remain closely linked during normal production.

The controller integrates 3 analog inputs for sensor feedback and 2 analog outputs for reference signaling. Its 11 digital inputs capture fast switching states, and 5 configurable digital I/O lines can be assigned as either inputs or outputs to match peripheral requirements. Network traffic passes through 2 Ethernet ports that follow the 100Base-TX standard and use RJ-45 8-pin connections, so deterministic communication is maintained across the Multi-Ethernet backbone. The interface electronics draw 2.7 W to power the integrated switch, leaving the main supply available for drive functions. This arrangement helps the controller exchange commands, device status, and application data with nearby automation components without requiring a separate external switch for basic network routing.

The primary encoder channel uses a Multi-Encoder Interface and is routed through a D-Sub 15-pin female connector. Its signal conditioning consumes 1.1 W, supporting precise position feedback without overloading the low-voltage rail. Three expansion bays are available as 3 optional slots, allowing additional modules for fieldbus communication or added I/O functions when the application requires them. Functional safety is handled by the Safe Motion package, and the dedicated circuitry requires 2.5 W for speed, standstill, and direction monitoring without external relays. The extended scope interface equipment also provides access to diagnostic traces and maintenance counters through the same Ethernet backbone, which helps simplify troubleshooting and operating-state review during machine operation.
