Product Description:

The CSB02.1B-ET-EC-EM-NN-DA-NN-AW drive controller is engineered by Bosch Rexroth Indramat within the CSB Drive Controllers series. Serving as the control section of an IndraDrive system, it pairs with a power module to regulate torque, speed, and position loops for servo and spindle motors used in material-handling, packaging, and machine-tool equipment. By translating fieldbus commands and encoder feedback into deterministic control signals, it synchronizes multiple mechanical axes in real-time industrial automation tasks. The controller handles the command-processing side of the drive, while a separate power unit supplies motor current. This modular layout supports installations that need coordinated motion across several axes with different load demands.

This control section offers 3 analog inputs for torque bias or velocity references and 2 analog outputs that return measured values to a PLC. A bank of 11 digital inputs handles limit switches, and five configurable I/Os cover diagnostics or handshake lines. All electronics run from a DC 24 V control supply, and logic circuits draw only 17 W, keeping cabinet heat low. Two probe inputs latch position during registration moves, and an I/O extension accepts digital or analog daughter cards to raise channel density. That mix of analog and digital channels supports both process references and discrete machine interlocks. The controller ships without integrated safety technology, so the surrounding system can use external safety hardware matched to the application.

For networked motion systems, the controller integrates Multi-Ethernet hardware that supports EtherNet/IP, EtherCAT, and Sercos through a single RJ45 pair. Feedback is processed by a Multi-Encoder Interface, and the Encoder Emulation channel can output virtual TTL or HTL signals at the 4 MHz RS-422 rate. The device sources these differential lines with 40 mA of single-ended current, which helps preserve signal integrity over long cables. Three optional slots remain free, allowing future fieldbus or safety modules without mechanical changes. This arrangement lets one controller platform fit different industrial networks without changing the main control section. The emulated output can feed downstream counters, motion monitors, or other devices that expect a conventional incremental signal.
