Product Description:
The CSB02.5B-ET-EC-NN-NN-DA-NN-FW is a compact drive controller from Bosch Rexroth Indramat in the CSB Drive Controllers series. It serves as the control center for servo and spindle axes by linking feedback devices, field networks, and local signals to generate precise position, speed, and torque commands. Designed for cabinet installation, the unit integrates motion logic, real-time Ethernet routing, and onboard diagnostics. This allows one module to coordinate multiple machine axes without relying on an external PLC for every motion task, which suits automated assembly cells, packaging equipment, and material-handling stages.
To meet networked factory requirements, the unit features a Multi-Ethernet interface with two RJ45 connectors, allowing simultaneous routing and device chaining. Encoder feeds are supported by an internal supply that delivers 500 mA at 12 V and 500 mA at 5 V, and it maintains signal integrity along cables up to 75 m. High-resolution feedback is supported by an analog bandwidth that limits sine signals to 400 kHz, while digital square-wave tracks are decoded up to 1000 kHz. This combination allows the controller to process both analog and digital encoder signals at high rates. The dual-port network layout also supports straightforward integration into line-based Ethernet topologies.
The motion section links mechanically to the HMU05 power module, and the multi-encoder interface supports incremental, sine-cosine, and absolute sensors on the same port type. The controller provides 11 digital inputs, two probe channels, five bidirectional digital lines, three analog inputs, and two analog outputs, while the DA expansion adds 6 DI, 2 DIO, 6 DO, 2 AI, and 2 AO. Each voltage input is converted at 14-bit resolution for consistent analog processing. Fast edge capture is enabled by probe inputs that accept pulses as short as 4 µs. The Ethernet hardware conforms to IEEE 802.3, and the dual relays can carry 1000 mA and switch loads up to 30 V for direct control of brakes or contactors.
