Product Description:
The CSB02.1B-ET-EC-EM-S4-NN-NN-NW is a drive controller module produced by Bosch Rexroth Indramat within the CSB Drive Controllers series. In an automation cell, it operates as the central axis controller, coordinating servo drives and exchanging motion data with the plant network. By managing encoder feedback, fieldbus communication, and safety functions in a single housing, the unit supports deterministic positioning for packaging equipment, pick-and-place gantries, and other high-throughput machines. Its centralized design also helps keep motion commands, feedback handling, and network communication aligned during synchronized machine operation.
Two analog outputs support current and voltage signals. The current channel is processed at a resolution of 11-bit, while the voltage channel reaches 13-bit resolution, giving fine setpoint adjustment for torque and speed loops. The controller accepts eleven digital inputs, and the count is 11, so it can accommodate limit switches, probes, or user diagnostics. Its EC measurement path uses a 12-bit converter and can capture encoder clock signals up to 1000 kHz, so high-resolution linear scales do not alias. The EM generator output produces position-simulated pulses at motor speed with a ceiling of 1 MHz. Real-time field communication is handled through the Multi-Ethernet port, allowing rapid integration with EtherNet/IP, PROFINET, EtherCAT, or Sercos networks. These interfaces let the controller connect motion control functions with auxiliary machine signals without requiring separate coordination hardware.
The Ethernet segment conforms to 100Base-TX and is presented on a shielded 8-pin RJ-45 jack, so standard cabling can be used without adapters. The multi-encoder interface accepts absolute or incremental sensors, and the controller can recreate feedback for downstream axes through an encoder emulator that outputs absolute SSI and incremental formats. Relay contacts provide signaling for brakes or external interlocks, and they can switch up to 1000 mA at 30 V. This allows the controller to exchange status signals with connected machine devices while maintaining clear separation between motion feedback and auxiliary control functions. Functional safety is delivered by the Safe Motion package, enabling safe torque off, safe stop, and other motion-related safety states.
