Product Description:
The CSB02.1B-ET-EC-NN-NN-NN-NN-AW is a drive controller module produced by Bosch Rexroth Indramat for the CSB Drive Controllers series. It serves as the command and power interface between a motion control PLC and one or more servo inverters, coordinating feedback, fieldbus traffic, and local I/O so that actuators in packaging, handling, and other industrial automation lines follow programmed velocity, torque, or position profiles. Internal link supervision verifies cable integrity, and the controller can report status through the configurable I/O so that supervisory PLC logic can respond quickly to faults or communication interruptions.
This controller is powered from a DC 24 V control supply and draws as little as 17 W during normal operation, which minimizes cabinet heat load. Network traffic is managed on a Multi-Ethernet bus running at 100Base-TX and presented on an 8-pin RJ-45 connector, allowing direct cabling to standard switches for straightforward network integration inside a control cabinet. Two ±10 V analog outputs, identified as 2 (±10 V), provide velocity or torque references for external drives, while 11 opto-isolated digital inputs accept limit switches, drive-ready contacts, or user commands. Additional interfaces include two probe inputs for high-resolution capture of edge events, a maximum pulse-width acceptance of 1 ms for time-critical latching, and an inrush current below 5 A so that system fusing can remain compact. The Ethernet electronics add only 2.7 W to the power budget, and copper pairs are carried on shielded twisted-pair cable to reduce noise on connected communication lines.
The controller has 5 configurable digital I/O lines that can be mapped individually as inputs or outputs to suit varied machine sequences. Feedback from motors or linear encoders connects through a multi-encoder interface; the unit supplies up to 500 mA at 5 V with a 6 W encoder power budget, supporting resolvers, TTL, or absolute serial formats without external supplies. The controller has 3 option card bays for system expansion, allowing combinations such as additional I/O blocks, safety modules, or alternative fieldbuses for application-specific layouts.
