This controller features a multi-encoder interface, STO safety function, and encoder emulation output.
Internal Product Review
The CSB02.1B-ET-EC-PB-L3-EM-NN-FW is a Bosch Rexroth Indramat CSB drive controller with Multi-Ethernet communication and a PROFIBUS fieldbus interface. Multi-Encoder support paired with encoder emulation feedback makes the unit especially useful for retrofit work and mixed-feedback automation systems. STO (Safe Torque Off) adds valuable machine protection and rounds out a very capable controller platform.

Product Description:
The CSB02.1B-ET-EC-PB-L3-EM-NN-FW is a drive controller produced by Bosch Rexroth Indramat within the CSB Drive Controllers series. It is designed to regulate servo or spindle axes in industrial automation lines, coordinating motion profiles and feedback signals between motors and higher-level PLCs. By housing communication, encoder processing, and safety circuits in a single rack-mountable unit, the controller simplifies cabinet wiring while maintaining deterministic control over connected drives.
A key feature is its Multi-Ethernet communication core, which can be configured for Sercos III, EtherCAT, EtherNet/IP, or PROFINET IO without hardware changes. All Ethernet channels comply with the IEEE 802.3 physical layer, allowing standard cabling and diagnostic tools. For legacy installations, the integrated fieldbus interface supports PROFIBUS, and wiring is completed through a shielded D-Sub 9-pin female connector so no external gateways are needed. Encoder feedback is handled by a multi-encoder interface that supplies 12 V and 5 V rails, each rated at 500 mA, providing adequate current for SSI, EnDat, or resolver feedback heads. When emulated feedback is required, the unit delivers differential A/B/Z signals through a D-Sub 15-pin male port, and the outgoing lines are limited to an effective cable capacitance of 60 pF/m to preserve signal integrity over long runs.
Drive-integrated functional safety is provided by the STO circuit, which removes energy from the power stage without mechanical contactors. The enable channel accepts control logic that meets IEC 61131, Type 2 requirements, so it can be wired directly to compliant safety PLC outputs. Once a stop command is asserted, the circuit can source up to 350 mA toward diagnostics or status LEDs, allowing field verification of the shutdown state.
