The RAC 3.5-150-460-APS-Z1-220, manufactured by Bosch Rexroth Indramat, is part of the RAC Spindle Drive Controllers series. This precision-engineered AC Main Spindle Drive Controller combines high power density with advanced control features for demanding industrial applications. Designed for machining centers and automated systems, it delivers reliable performance under continuous operation. Its compact form factor simplifies integration with standard 19-inch control racks.



Dense power electronics accept a Rated Connection Voltage of 3 x AC 400 V, 50 Hz, +/-15% or 3 x AC 460 V and supply a continuous Rated Current of 150 A to the spindle, while an onboard Additional Bleeder ensures safe discharge of DC bus capacitors. Control electronics operate at AC 230 V / 50-60 Hz on a dedicated Rated Connection for Control Electronics, isolating command logic from high-power circuits. Thermal management is handled by an Internal Blower / Built-in fan cooling system that maintains optimal junction temperatures. The unit features an Additional Interface via Serial interface RS 232-C and a precision Additional Encoder Input for the high-resolution INDRAMAT encoder, all wired through a 9-pole Interface Terminal X4.



Analogue Speed Command (+/- 10 V) input and proven industrial-grade design enable seamless integration with CNC systems and process controllers. Running on the stable Series 3, Version 5 hardware platform, it delivers consistent reliability under continuous load, minimizing downtime. Ideal for high-speed milling, grinding spindles, and turning centers, this controller ensures precise torque control and rapid response in automated manufacturing cells.
