Product Description:

The CSB02.1B-ET-EC-CN-NN-NN-NN-FW is a drive controller produced by Bosch Rexroth Indramat in the CSB Drive Controllers series. As a modular automation component, the unit processes fieldbus traffic, encoder feedback, and I/O states to regulate connected servo drives inside machine tools, packaging lines, and handling modules. Its design consolidates network interfaces, signal conversion, and low-voltage power management so machine builders can coordinate motion axes through a single-slot device rather than discrete cards. This arrangement reduces panel area and keeps control functions centralized within the drive system.

The controller integrates 11 digital inputs for fast position latching, while 5 configurable digital I/O lines can be assigned as status outputs or additional command channels. For process variables such as pressure or temperature, it provides 3 analog inputs that are digitized by a 12-bit EC A/D converter, and setpoint data can be sent to external devices through 2 analog outputs. Two fast latch circuits are available as 2 probe inputs for edge-triggered measurements on high-precision axes. Signal timing is synchronized through the Multi-Encoder Interface and a 400 kHz EC sine cutoff filter, allowing the control section to manage multiple signal types within one module.

Fieldbus communication is handled by a D-Sub 9-pin CANopen port that supports up to 127 CANopen nodes and by an RJ-45 8-pin socket that links the Multi-Ethernet stack to 100Base-TX networks. Deterministic exchange of cyclic and acyclic data is maintained across both media. Encoder data with square-wave signals is captured at up to 1000 kHz, ensuring compatibility with high-resolution feedback devices and clean detection of incremental tracks. The module draws logic power from a 24 V DC supply, and its internal electronics dissipate no more than 17 W, allowing passive cabinet cooling without additional fans.
