Product Description:

The CSB02.1B-ET-EC-EC-S5-NN-NN-AW is a motion drive controller produced by Bosch Rexroth Indramat as part of the CSB Drive Controllers series. Installed inside electrical cabinets, the unit interfaces with servo inverters and feedback devices to execute position, velocity, and torque commands in industrial automation cells. It supplies control logic, safety monitoring, and fieldbus communication so that packaging stations, handling gantries, or processing lines follow exact motion trajectories demanded by their PLC or CNC host.

This model manages up to 1 axis, focusing its processing resources on a single mechanical drive for predictable cycle times. Command traffic moves through the integrated MultiEthernet port, allowing the controller to appear as an Ethernet/IP, PROFINET, or EtherCAT node without additional hardware. Local reaction inputs are available through 11 digital inputs, and machine states can be signaled outward through 5 configurable digital I/O points. Two ±10 V analog outputs supplement the digital channels for analog drive or sensor feedback. Feedback devices are accepted on 2 encoder interfaces, while an internal resolver evaluation circuit supports legacy motor transducers. The enclosure measures 241 mm in height and 103 mm in depth, and it provides three optional slots for technology or communication add-ins.

The controller incorporates 2 probe inputs for high-speed position latching during reference moves or quality checks. Its functional safety layer is classified as Safe Motion, which supervises velocity, position, and direction against application limits. Two independent safety encoder evaluation channels tie the motion logic to certified feedback, and network segmentation can be achieved with up to 35 safety zone nodes so that multiple machines can share one controller while maintaining individual stop areas. Despite these functions, the unit weighs only 0.480 kg, which simplifies DIN rail mounting and supports dense cabinet layouts without exceeding load limits.
