RAC 2.2-200-460-API-W1

The Bosch Rexroth Indramat RAC 2.2-200-460-API-W1 from the RAC Spindle Drive Controllers series is a high-performance AC Main Spindle Drive Controller designed to meet rigorous industrial demands. It operates on a Rated Connection Voltage of 3 x AC 400 V, 50 Hz, \u00b115% or 3 x AC 460 V, and delivers a solid Rated Current of 200 A for precision spindle regulation. Internal thermal management is handled by an Internal Blower / Built-in fan configuration that ensures stable operation under continuous load. The compact, rugged housing omits an Additional Bleeder, optimizing reliability and eliminating unnecessary components.

Spindle feedback and motion synchronization are supported via a High-resolution INDRAMAT encoder (~) and an Additional encoder input for spindle feedback, enabling sub-micron positioning accuracy. Command signals are accepted through an analogue Speed Command (+/-10 V) interface, while the Incremental encoder output and an Interface Terminal X4, 9 poles furnish straightforward connectivity to CNC or PLC systems. The design adheres to Series 2 specifications and is marked as Version 2, assuring compatibility with existing Bosch Rexroth Indramat architecture. This drive's I/O mapping and diagnostic access simplify commissioning, fault tracing, and firmware updates on the production floor.

Engineers will appreciate that no extraneous bleeder circuits are fitted, reducing MTTR and enhancing mean time between failures. Whether deployed in high-speed milling, grinding spindles, or multi-axis turning centers, the RAC 2.2-200-460-API-W1 excels at maintaining spindle speed stability under variable mechanical loads. Its seamless integration into modular automation cells and standardized electrical interfaces make it an essential component for modern, precision-driven manufacturing environments.
