Product Description:
The CSB02.1B-ET-EC-EC-S5-DA-NN-FW is a drive controller in the CSB Drive Controllers series produced by Bosch Rexroth Indramat. It serves as the intermediary between a higher-level motion computer and connected servo or spindle motors, executing current, velocity, and position loops for automated machinery. By coordinating encoder feedback and forwarding deterministic status data, the device supports precise motion sequences required in packaging, material handling, and assembly cells.
High-speed signal handling starts at the analog stage. An output conversion time of 250 µs lets the controller refresh reference voltages four thousand times per second. Incoming command voltages are digitized at 14-bit resolution, providing 16,384 discrete steps for fine torque or speed control. Network traffic is routed through the integrated Multi-Ethernet interface, allowing the same hardware to join PROFINET, EtherNet/IP, or EtherCAT segments without additional option cards. Two motion feedback channels are available through the 2 × Multi-Encoder interface, enabling simultaneous evaluation of primary and secondary position sensors. Each encoder port is powered by a dedicated supply that can source up to 500 mA, which is sufficient for high-resolution optical or magnetic encoders. Additional hardware features include three optional slots, digital and analog I/O expansion, a sine input cut-off of 400 kHz, and square-wave compatibility to 1000 kHz.
On the Ethernet layer, compliance with 100Base-TX is provided through a shielded RJ-45 (8-pin) connector, so standard Cat5e cabling can carry deterministic network cycles. Resolver feedback is energized at 8 kHz, maintaining stable amplitude over long cable runs. Safe Motion technology at level S5 is supported, and the dedicated safety output can deliver up to 350 mA for external relays or contactors. Two independent encoder evaluations enable STO, SS1, or SLS functions without an external safety PLC, while the digital and analog I/O extension path allows additional process sensors to link high-frequency measurement channels with plant diagnostics.
