RAC 3.5-200-460-L00-W1-220

The Bosch Rexroth Indramat RAC 3.5-200-460-L00-W1-220 from the RAC Spindle Drive Controllers series is a high-performance AC Main Spindle Drive Controller engineered for precision and reliability. It operates on a Rated Connection Voltage of 3 x AC 400 V, 50 Hz, +/-15% or 3 x AC 460 V and delivers continuous power through a robust Rated Current of 200 A. This controller features an integrated thermal management system with an Internal Blower / Built-in fan for efficient heat dissipation under heavy-duty spindle loads. Designed for seamless integration, it supports a Speed Command via the SERCOS interface and precise position monitoring through an Interface Terminal X4 optical waveguide connection.

The drive’s control electronics are powered by a dedicated Rated Connection for Control Electronics of AC 230 V / 50-60 Hz, ensuring stable auxiliary supply independent of the main bus. It is provided Without additional encoder input and Without additional bleeder, reducing complexity and enhancing system robustness. Compact yet modular, the unit is identified as Series 3, Version 5, offering consistent form factor and firmware features across installations. A Speed Set-Point of 10V allows fine-tuned velocity adjustments, and the SERCOS protocol guarantees jitter-free communication with modern CNC and PLC systems.

Engineered for industrial spindles, the RAC 3.5-200-460-L00-W1-220 facilitates rapid commissioning and minimal maintenance through its pluggable optical connectors and standardized mounting footprint. Its durable design accommodates harsh shop-floor environments while maintaining tight speed regulation and torque control. Whether applied in milling, grinding, or high-speed drilling centers, this spindle drive controller delivers reliable performance and precise motion control for complex machining operations.
