Product Description:

The CSB02.1B-ET-EC-PB-L3-DA-NN-FW is a compact drive controller produced by Bosch Rexroth Indramat within the CSB Drive Controllers series. It coordinates servo axes, collects local I/O, and enforces safety, allowing the automation host to delegate time-critical motion and interlock tasks to the module. By combining integrated networking with programmable signal conditioning, the unit adds deterministic drive regulation to packaging machines, material-handling lines, and other multi-axis installations. Its compact layout lets motion control, safety handling, and local signal exchange stay in one device instead of being distributed across several separate modules. That arrangement helps the controller react to changing axis conditions without waiting for every low-level decision from the main automation system.

This controller provides three analog inputs and two analog outputs. Both signal directions share a ±10 V span, permitting standardized transducer and drive references. Output granularity is 24 mV/Incr, so a host PLC can command fine torque or speed setpoints. The unit also has 11 digital inputs for limit switches and sensors, while the sourcing outputs can deliver 500 mA to energize contactors or indicator lamps. A built-in Safe Torque Off circuit removes motor power through hardware gating when a safety channel trips. The analog and digital channels allow the controller to process machine status signals locally, which reduces the need for separate interface hardware in the control cabinet. This arrangement supports analog monitoring, command generation, and discrete machine signaling from the same controller.

Network connectivity is provided by a Multi-Ethernet port set that can present several industrial Ethernet protocols without changing hardware. For legacy or hybrid installations, the integrated PROFIBUS channel communicates through a D-Sub 9-pin female connector, and its physical layer is RS485, enabling standard segment lengths. Motion feedback is accepted through a multi-encoder interface that adapts to incremental or absolute transducers, so the controller can work with different feedback devices across mixed machine layouts. The voltage inputs digitize signals at a resolution of 14 Bit, matching the precision of the analog outputs for symmetrical loop accuracy. It also allows the same hardware platform to remain usable in systems that mix newer Ethernet links with existing fieldbus connections.
