RAC 3.5-200-460-A00-Z1-220

The Bosch Rexroth Indramat RAC 3.5-200-460-A00-Z1-220 from the RAC Spindle Drive Controllers series is an advanced AC Main Spindle Drive Controller engineered for precision spindle applications. It operates on a Rated Connection Voltage: 3 x AC 400 V, 50 Hz, +/-15% or 3 x AC 460 V input and delivers a continuous Rated Current: 200 A to drive high-speed spindles. The controller’s electronics are powered by a separate Rated Connection for Control Electronics: AC 230 V / 50-60 Hz supply, ensuring stable logic operation under heavy load. A robust Interface Terminal: X4, 9 poles provides secure connections for power and control signals.

The unit features an Internal Blower / Built-in fan cooling system that maintains optimal thermal conditions within the compact enclosure. Speed feedback is handled via an Analogue (+/- 10 V) Speed Command input, enabling smooth acceleration and deceleration profiles. It includes an Additional Bleeder circuit to safely discharge DC bus energy when the drive is shut down, though it ships Without additional encoder input for simplified installations. This controller is identified as Series 3, Version 5, reflecting the third-generation hardware platform with firmware-level enhancements for real-time spindle monitoring.

Designed for seamless integration into CNC machining centers and milling systems, the RAC 3.5-200-460-A00-Z1-220 offers rugged reliability and precise speed control. Its internal fan and additional bleeder reduce external component requirements, while the analog speed command interface supports legacy and modern control architectures alike. With Bosch Rexroth Indramat quality built in, this series controller is ideal for high-duty-cycle environments that demand consistent torque delivery and minimal downtime.
