RAC 2.2-200-460-DPD-W1

RAC 2.2-200-460-DPD-W1, manufactured by Bosch Rexroth Indramat and part of the RAC Spindle Drive Controllers series, is a high-performance AC main spindle drive controller designed to meet demanding industrial requirements. It accepts a Rated Connection Voltage of 3 x AC 400 V, 50 Hz, +/-15% or 3 x AC 460 V, ensuring compatibility with global power standards. The compact, rugged housing incorporates an Internal Blower / Built-in fan for effective thermal management, while maintaining a streamlined footprint. Its versatile design supports both standard and heavy-duty spindle applications without the need for external cooling accessories.

Offering a continuous Rated Current of 200 A, the drive delivers precise speed regulation via a Speed Command input of Digital (16 bit parallel) resolution. It features a Digital position set-point (16 bit parallel) as an Additional Interface, enabling deterministic control loops. Advanced feedback is achieved through an Additional encoder input for spindle feedback compatible with a High-resolution INDRAMAT encoder (~). Connectivity is facilitated by a robust Interface Terminal X4, 25 poles, while the unit’s design is specified as AC Main Spindle Drive Controller in Version 2 of the Series 2 family. The absence of an Additional Bleeder option simplifies maintenance and reduces component count.

Integration into automated machining cells is streamlined by the drive’s native digital interfaces and encoder compatibility, enabling rapid commissioning and seamless PLC communication. Built-in cooling and encoder feedback ensure reliable performance under continuous duty, minimizing thermal drift and spindle runout. This combination of precision, robustness, and simplified system architecture makes the RAC 2.2-200-460-DPD-W1 an ideal choice for high-speed, high-torque spindle applications in aerospace, automotive, and general manufacturing environments.
