Product Description:

The CSB02.1B-ET-EC-EC-NN-EM-NN-AW is a drive controller module from Bosch Rexroth Indramat that belongs to the CSB Drive Controllers series. Intended for cabinet installation with IndraDrive power sections, it orchestrates motion tasks by linking servo drives to higher-level PLC platforms through integrated network ports. Within an automation cell, it delivers closed-loop control, diagnostics, and coordinated axis handling, acting as a key bridge between field-level feedback devices and machine sequencing software.

The controller’s field connectivity is centered on Multi-Ethernet, allowing real-time data exchange over PROFINET, EtherNet/IP, and similar protocols through an RJ-45 8-pin interface that follows the 100Base-TX physical layer. It accepts 11 discrete digital inputs for state monitoring, and its logic electronics are powered from a DC 24 V auxiliary supply that isolates control circuitry from the drive bus. Two Multi-Encoder ports read incremental or absolute transducers, while the SSI emulation function forwards absolute position values to legacy masters. Dual probe inputs capture edge-triggered events for registration applications, and the unit does not include integrated safety technology, so external safety relays or controllers are required where those functions are needed.

Additional resources on the CSB02.1B platform support flexible signal handling. 2 analog outputs provide ±10 V speed or torque references, and 5 configurable digital I/O points can be mapped as command or status lines to external devices. Expansion is possible through 3 optional slots that accept add-on cards for specialized feedback or extra communication channels. A built-in relay can carry up to 1000 mA, switching circuits that operate at 30 V, which is suitable for contactor control or alarm lamps. This mix of analog, digital, and expansion functions lets the controller connect to external signaling, feedback, and auxiliary control circuits within a machine section.
