RAC 2.2-200-460-AP0-W1

The RAC 2.2-200-460-AP0-W1, Bosch Rexroth Indramat, RAC Spindle Drive Controllers unit delivers premium spindle control for high-performance automation applications. This AC main spindle drive controller is engineered to power 2AD asynchronous and 1MB frameless spindle motors with continuous outputs up to 55 kW. Its robust design accommodates a wide supply range and supports demanding CNC requirements. The combination of precision feedback and regenerative capability makes it a versatile cornerstone for advanced spindle systems.

In its technical specification, the controller accepts a Rated Connection Voltage of 3 x AC 400 V, 50 Hz, ±15 % or 3 x AC 460 V and operates as an Device Type AC main spindle drive. It delivers a Rated Current of 200 A continuously at a peak regenerative output of 55 kW for up to 5 seconds, all without an Additional Bleeder. Magnetic interference is managed via an internal blower and built-in fan under the Cooling scheme, ensuring stabilized temperatures between +5 °C and +45 °C. Position feedback integrates through an Additional Encoder Input, interfacing a high-resolution INDRAMAT encoder (Encoder Type) via the 9-pole Interface Terminal X4. Speed is governed through an analogue Speed Command of ±10 V for seamless synchronization within multi-axis systems.

Engineered for reliability, the RAC 2.2-200-460-AP0-W1 employs rugged construction and precise thermal management to maintain peak efficiency at altitudes up to 1000 m. Its plug-and-play encoder input and standardised terminal X4 accelerate installation and commissioning. This controller’s proven performance under continuous load makes it ideal for CNC machining centers, high-speed drilling spindles, and automated milling applications, where consistent torque, rapid response, and robust integration are essential.
