Product Description:
The CSB02.1B-ET-EC-NN-S5-DA-NN-FW belongs to the CSB Drive Controllers series manufactured by Bosch Rexroth Indramat. It is a modular control section that integrates with servo power stages to regulate motor torque, speed, and position in industrial automation lines. The unit consolidates signal conversion, feedback evaluation, and network interfacing so machine builders can synchronize multiple axes and embed safety functions within a compact drive cabinet. Because it works with separate power stages, the control section focuses on command processing, feedback handling, and communication rather than direct power conversion.
The voltage channel offers 14-bit granularity while the current channel is resolved at 12-bit, allowing fine scaling of ±10 V command levels. The unit has 2 analog outputs for reference signals, which supports coordinated control without external converters. It also provides 11 digital inputs for fast position latching, along with five configurable digital I/O points that can be reassigned for process events. Base electronics dissipate 17 W under nominal load, so cabinet thermal planning remains straightforward. The multi-encoder interface accepts incremental and absolute feedback, allowing the controller to process rotor position from several sensor formats. This mix of analog, digital, and feedback interfaces allows the control section to connect process signals and motor feedback within the same module.
Field communication relies on the Multi-Ethernet option, which uses RJ-45, 8-pin connectors and operates at 100Base-TX in accordance with IEEE 802.3u. A maximum output pulse width of 1 ms is available on the high-speed outputs, so trigger signals can be generated for laser marking or camera strobes. When extended I/O is required, a digital and analog extension board can be attached to expand connectivity. Functional safety is delivered by the Safe Motion S5 package, and its dedicated circuitry draws 2.5 W while the separate ET module adds 2.7 W for Ethernet tasks. Ethernet communication and safety functions are handled by dedicated modules within the same control section.
