RAC 2.3-200-380-L00-W1

The Bosch Rexroth Indramat RAC 2.3-200-380-L00-W1 from the RAC Spindle Drive Controllers series is a high-performance AC Main Spindle Drive Controller designed for demanding CNC and industrial machining applications. With a rated connection voltage of 3 x AC 400 V, 50-60 Hz and a robust rated current of 200 A, this controller delivers precise power handling for heavy-duty spindles. The unit operates with a speed set-point of 10 V input and leverages an internal blower / built-in fan cooling system to maintain optimal thermal stability under continuous load. Compact yet powerful, the RAC 2.3-200-380-L00-W1 ensures predictable motor behavior and extended uptime.

Featuring advanced communication, the controller provides a native SERCOS interface for high-resolution speed command feedback and synchronization across multi-axis systems. The Interface Terminal X4 with optical waveguides ensures secure, high-bandwidth data transfer while isolating noise from drive electronics. This Version 3 unit in Series 2 architecture omits an additional encoder input for simplified wiring and operates without an additional bleeder to reduce component complexity. Integrated system diagnostics monitor current, voltage, and thermal conditions, empowering maintenance teams to perform predictive servicing.

Built for precision and reliability, the RAC 2.3-200-380-L00-W1 excels in milling, grinding, and turning centers where dynamic torque response is critical. Its streamlined design and standardized footprint accelerate retrofit projects and new machine builds, while the rugged internal components withstand shock and vibration common in high-speed spindles. The result is a dependable spindle drive solution that enhances throughput and maximizes machine tool availability.
