Product Description:

The CSB02.1B-ET-EC-NN-S4-NN-NN-FW is a drive controller manufactured by Bosch Rexroth Indramat for the CSB Drive Controllers series. It serves as the command section in multi-axis systems, combining servo regulation, I/O processing, and network routing so that separate power sections can handle motor switching. By managing motion profiles, feedback evaluation, and diagnostic reporting, the unit supports synchronized operation in conveyors, pick-and-place modules, and other automated stations that rely on repeatable cycle timing. Its role within the system is to coordinate control functions while the connected power stage supplies the motor current.

This controller operates from a 24 VDC control supply and draws only 17 W, which helps limit demand on cabinet power distribution. It provides 11 isolated digital inputs for field signals, along with five configurable lines for mixed digital I/O tasks and five additional dedicated input/output points. Two ±10 V analog outputs deliver command signals, and voltage-based feedback is processed with 13-bit resolution, while current signals are handled with 11-bit depth. High-speed communication is handled through a Multi-Ethernet interface module, and the multi-encoder port can read EnDat, SSI, or incremental sensors without additional interface cards. Three optional slots allow later expansion for fieldbus or safety functions, and the available I/O resources support connection of sensors, analog references, and status signals within the same control platform.

Integrated Safe Motion functions maintain safe machine states independently of the application code. For discrete actuator control, an internal relay can switch up to 1000 mA at 30 V without requiring an external amplifier. Output pulses can be generated as short as 1 ms for accurate latching tasks, and two probe inputs are available for edge capture during motion events. The extended-scope interface equipment provides oscilloscope and parameter-trace tools for monitoring controller behavior during operation. These monitoring functions help track signal activity and controller response during normal machine use.
