Product Description:

The CSB02.1B-ET-EC-EM-S4-NN-NN-AW drive controller is produced by Bosch Rexroth Indramat as part of the CSB Drive Controllers series. It is intended to manage servo axes and ancillary actuators within automated machinery, converting fieldbus commands into precise current and velocity profiles for connected motors. By integrating motion logic, input processing, and network interfaces in a single housing, the unit acts as the central node of a distributed motion system used in packaging lines, pick-and-place gantries, and material-handling stations.

The controller accepts position or process feedback through an analog channel with 13-bit resolution, giving 8,192 discrete steps for each captured value. It returns actuator status through 2 analog outputs, a feature often used to mirror torque or speed for external indicators. Command sequencing is supported by 11 digital inputs, while an additional set of five configurable I/O points can be assigned as triggers, latches, or diagnostic flags. For time-critical edge detection, the hardware offers two probe inputs, and three optional slots allow fieldbus or memory expansion. Network traffic moves across a Multi-Ethernet backbone, and determinism is maintained by the integrated 100Base-TX link layer.

Axis feedback is handled by an Encoder Emulation channel that reproduces incremental signals for legacy controls and by a multi-encoder interface that supplies 5 V or 12 V excitation at 500 mA for each transducer. The Safe Motion package supervises velocity, standstill, and direction, and it releases a dedicated output limited to 350 mA to drive external contactors. Communication with safeguarding light curtains or e-stops passes through the same configurable I/O, so wiring stays compact. The Ethernet stack exits the housing on a RJ-45, 8-pin connector, keeping compatibility with standard patch cords.
