RAC 2.3-250-380-API-W1

The Bosch Rexroth Indramat RAC 2.3-250-380-API-W1 from the RAC Spindle Drive Controllers series delivers precision spindle control in a robust AC main drive package. This Device Type: AC Main Spindle Drive Controller accepts a Rated Connection Voltage of 3 x AC 400 V, 50-60 Hz and supports a Rated Current of 250 A, making it suitable for high-demand machining centers. Built-in connectivity includes anstrong>Incremental encoder output and an Additional encoder input for spindle feedback, enabling closed-loop position and speed monitoring. The controller’s Interface Terminal X4, 9 poles simplifies field wiring and integration into existing control architectures.

Designed for optimal thermal management, the RAC 2.3-250-380-API-W1 employs an Internal Blower / Built-in fan cooling system to maintain stable operation under continuous loads. It interfaces via a versatile Analogue (+/- 10 V) Speed Command input, ensuring smooth acceleration profiles and rapid response to control signals. The drive omits an Additional Bleeder, streamlining the power stage and reducing maintenance points. A High-resolution INDRAMAT encoder (~) Encoder Type guarantees precise angular feedback, while the Additional Interface options support diverse automation environments and spindle architectures.

Versioned as Series 2, Version 3, this spindle drive controller combines proven reliability with modern control features. Its compact footprint and standardized mechanical design simplify cabinet layouts and spare-parts management across installation sites. For manufacturers seeking high-torque, high-precision spindle regulation in demanding industrial applications, the RAC spindle drive offers a balanced blend of power, accuracy, and serviceability.
