Product Description:

The CSB02.1B-ET-EC-EP-S5-NN-NN-FW is a compact drive controller produced by Bosch Rexroth Indramat for use in multi-axis automation. As part of the CSB Drive Controllers series, it closes the control loop between the machine PLC and connected servo drives, converting network commands into precisely timed current and position signals. The unit is intended for enclosure mounting inside packaging, material-handling, and assembly cells where deterministic Ethernet networking and integrated local inputs and outputs can simplify panel layouts and reduce setup effort.

The controller provides 3 analog inputs and 2 analog outputs, each sampled at 13-bit voltage resolution to capture sensor feedback and issue proportional control signals without external converters. Eleven discrete channels are available through 11 digital inputs, allowing direct connection of limit switches, start commands, or fault contacts. Fieldbus messaging runs through the integrated ET Multi-Ethernet interface, which accepts EtherCAT, Ethernet/IP, and PROFINET telegrams on the same port to streamline wiring. During idle operation, the electronics draw a 17 W base power consumption, so heat dissipation demands remain modest even in densely packed cabinets.

For motion capture, it carries two probe inputs that register edge events with a 4 µs pulse width, while five configurable I/O points can be assigned as additional feedback, trigger, or handshake signals. Three optional slots permit encoder or communication add-ons, and the internal regulator provides a 12 W encoder supply budget for SSI, EnDat, or Hiperface sensors. Functional safety is based on IEC 61131 Type 1 inputs and onboard S5 Safe Motion logic. The safety output can source up to 350 mA, enabling direct connection of contactors or brake relays without extra drivers.
