Product Description:

The CSB02.1B-ET-EC-PB-S5-NN-NN-FW belongs to the CSB Drive Controllers series produced by Bosch Rexroth Indramat. It is a compact single-axis control unit intended for industrial automation tasks that require coordinated servo operation, integrated safety, and multiple network options. By combining drive regulation, I/O handling, and field communication in one housing, the controller reduces panel space and simplifies machine wiring.

An axis count of 1 means the device manages one motor channel, which suits feeders, positioning tables, or auxiliary axes. Internal electronics draw up to a maximum of 17 W, so cabinet thermal load remains low. Motion commands can be issued through Multi-Ethernet, while the internal analog interface accepts and sources signals across a ±10 V range; feedback is digitized with 13-bit resolution for fine setpoint trimming. The unit has 11 digital inputs, allowing sensors or limit switches to be read directly, and a bank of five configurable digital I/O lines accommodates auxiliary tasks such as handshake signaling. The multi-encoder port supports EnDat, Hiperface, and resolver feedback, sourcing 500 mA at 5 V for transducer power. Analog output, analog voltage input, and the resolver supply frequency are synchronized by the internal timing logic. A safety output rated at 350 mA can energize external contactors when the drive’s Safe Motion functions are active.

Functional safety is governed by Safe Motion S5, enabling certified speed, position, and stop monitoring without extra relays. During power-up, the converter limits surge to less than 5 A of inrush current for no longer than 1 ms, protecting upstream breakers. The resolver reference carrier is generated at 8 kHz, ensuring adequate resolution for high-speed feedback decoding. For higher-level cell control, the integrated fieldbus port supports PROFIBUS, allowing deterministic command exchange alongside the Ethernet channel.
