RAC 2.3-150-460-A00-Z1

The Bosch Rexroth Indramat RAC 2.3-150-460-A00-Z1 from the RAC Spindle Drive Controllers series is a high-performance AC Main Spindle Drive Controller designed for demanding industrial applications. 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 robust Rated Current of 150 A for continuous spindle operation. An Internal Blower / Built-in fan provides effective thermal management, while the Analogue (+/- 10 V) Speed Command ensures precise speed regulation. The unit supports With additional bleeder circuitry and is classified as Series 2, Version 3 for compatibility with legacy systems.

Integration is streamlined via a X4, 9 poles Interface Terminal, and the controller operates reliably Without additional encoder input for straightforward installation. The modular design accommodates a built-in fan and bleeder resistor, minimizing external components and simplifying cabinet layouts. A microprocessor-based control architecture ensures rapid fault response and consistent torque delivery across the spindle’s speed range. This controller’s compact footprint and standardized series design allow easy upgrades within Bosch Rexroth Indramat drive families.

Engineered for demanding spindle applications, the RAC 2.3-150-460-A00-Z1 achieves precise speed and torque control through its analogue command interface. With proper cabinet cooling to maintain internal temperatures below 45 °C, this drive sustains peak performance without derating. The result is a reliable spindle drive solution for high-stiffness machine tools and continuous-duty processes.
