RAC 2.3-200-460-LQ0-W1

The Bosch Rexroth Indramat RAC 2.3-200-460-LQ0-W1 from the RAC Spindle Drive Series is a high-performance Device Type: AC Main Spindle Drive Controller engineered for precision machining and robust spindle control. It operates on a Rated Connection Voltage of 3 x AC 400 V, 50 Hz, +/–15% or 3 x AC 460 V and delivers a continuous Rated Current of 200 A for demanding load profiles. The drive’s Speed Command via SERCOS interface ensures deterministic communication, while the Speed Set-Point input of 10V provides analog flexibility for legacy systems. Integration is simplified through the Interface Terminal X4 with optical waveguides, and the design omits an Additional Bleeder, reducing component count without sacrificing performance.

Built-in thermal management relies on an Internal Blower / Built-in fan to maintain optimal junction temperatures even under sustained peak currents. The controller’s compact footprint houses versioning that tracks both Series 2 and Version 3 iterations for streamlined firmware compatibility. Its hardened optical interface resists electromagnetic interference, ensuring reliable feedback loops in electrically noisy environments. Modular heat sinks and fan assemblies accelerate servicing, while the omission of external bleeder resistors lowers maintenance overhead.

This spindle drive controller pairs effortlessly with CNC systems and rack-mounted power modules, offering a plug-and-play solution for lathe and mill applications. Its durable construction and precise current control make it ideal for high-speed spindles where accuracy and repeatability are critical. The RAC 2.3-200-460-LQ0-W1 sets a new standard for industrial spindle drives, combining efficient cooling, high current capacity, and advanced digital interfacing.
