Product Description:

The CSB02.5B-ET-EC-NN-NN-NN-NN-FW is a drive controller manufactured by Bosch Rexroth Indramat for the CSB Drive Controllers series. Deployed with an HMU05 power section, it forms a compact single-axis control package that closes current, velocity, and position loops for servo or induction motors. Within automated cells, the unit converts PLC motion commands into precisely timed drive signals, allowing machinery to maintain repeatable speed, torque, and positional accuracy. Its role is to coordinate the control layer and the connected power stage so the axis responds predictably during indexing, speed changes, and positioning tasks.

For local process interfacing, the controller offers 3 analog inputs that accept signals up to 1.3 kHz. Each channel is digitized at 14 bit resolution for fine loop tuning and stable reference processing. Discrete sensing is handled through 11 digital inputs, while actuators can be driven from two analog output channels and a transistor stage that sources up to 500 mA. An internal 30 V relay path is provided for auxiliary switching, and the integrated multi-encoder interface accepts incremental or absolute feedback devices without external adapters. This allows the controller to read field sensors, process position information, and send analog or digital commands to nearby devices in real time.

A Multi-Ethernet backplane supports deterministic messaging over EtherNet/IP, EtherCAT, sercos III, and PROFINET IO, letting the axis join heterogeneous network architectures without hardware changes. When the three optional slots are populated, additional safety or technology modules can be added without exceeding the board's 17 W dissipation budget. All control electronics are supplied from a monitored DC 24 V source, which keeps logic power separate from the drive's mains-fed inverter stage. The monitored control supply supports stable operation for communication, feedback handling, and local I/O functions in compact industrial enclosures.
