Product Description:

The CSB02.1B-ET-EC-PB-L3-NN-NN-FW is a controller module produced by Bosch Rexroth Indramat within the CSB Drive Controllers series. Designed for multi-axis servo applications, the unit links power electronics with motion control logic so that connected drives receive precisely timed commands in industrial automation cells. By combining real-time Ethernet, fieldbus signaling, and local I/O, it coordinates torque, speed, and position loops for packaging, material-handling, and assembly machinery. Its compact design fits into decentralized cabinets while remaining compatible with the IndraWorks engineering environment used for system setup and diagnostics.

This controller offers 2 analog output channels for transducer or actuator references and accepts three analog inputs for feedback or process values. It supports 11 dedicated digital inputs and five lines that can be configured as inputs or outputs, allowing event-driven tasks to be mapped directly to the control logic. Communication with higher-level PLCs is handled by the Multi-Ethernet interface; the copper port uses the 100Base-TX standard through an 8-pin RJ-45 connector and supports cyclic data exchange. A separate PROFIBUS port is present for gateway operation. The integrated Multi-Encoder interface supplies up to 6 W at 500 mA, so absolute or incremental encoders can be energized without external supplies. Two probe inputs capture high-resolution position latches for synchronized process triggers.

In addition to the communication and feedback resources above, the unit includes the STO (Safe Torque Off) function so that drive power can be removed immediately from connected axes when a safety channel is tripped. Three optional slots provide expansion for additional protocols or onboard logic, with the base unit automatically detecting 3 plug-in cards during startup. For peripheral control, an internal relay can switch loads up to 1000 mA at 30 V, making it suitable for contactors, brakes, or pilot lamps.
