RAC 2.3-250-460-D0I-W1

RAC 2.3-250-460-D0I-W1, Bosch Rexroth Indramat, RAC Spindle Drive Controllers deliver high-performance spindle control in a rugged, industrial-grade enclosure. This AC Main Spindle Drive Controller accepts a 3 x AC 400 V, 50 Hz, +/-15% or 3 x AC 460 V input and continuously supplies 250 A for demanding machining and grinding applications. The controller’s compact footprint and optimized electronics architecture minimize cabinet space while maximizing power density. Built by Bosch Rexroth Indramat, the RAC 2.3-250-460-D0I-W1 ensures precise rotational speed and torque management under heavy loads.

Engineered with a built-in fan and Internal Blower cooling system, the unit maintains stable operation even at elevated ambient temperatures. The digital Speed Command interface (16 bit parallel) offers microsecond-level response and direct integration with high-speed motion controllers. An incremental Additional Interface for encoder output provides real-time position feedback to higher-level PLCs, while the 25-pole Interface Terminal (X4) simplifies field wiring. This version 3 controller omits an Additional Bleeder and Additional Encoder Input, streamlining the power stage for pure spindle drive functions. The integrated control board (Series 2) embeds advanced safety algorithms, ensuring fast fault detection and shutdown.

By leveraging Bosch Rexroth Indramat’s modular design, the RAC 2.3-250-460-D0I-W1 integrates seamlessly into multi-axis milling centers, lathes, and grinding machines. Its robust construction and high overload tolerance contribute to exceptional reliability and uptime in continuous-production environments. Precise digital speed control and encoder integration equip manufacturers with the performance needed for tight-tolerance machining and complex surface finishing.
