RAC 2.2-200-460-D0S-W1

RAC 2.2-200-460-D0S-W1, manufactured by Bosch Rexroth Indramat, is part of the high-performance RAC Spindle Drive Controllers series. This AC Main Spindle Drive Controller is engineered to operate on a robust Rated Connection Voltage of 3 x AC 400 V, 50 Hz, ±15% or 3 x AC 460 V, providing a continuous output at a Rated Current of 200 A. As a Version 2 unit in Series 2, the RAC 2.2-200-460-D0S-W1 delivers consistent torque and speed regulation for demanding spindle applications. Its internal architecture is designed for compact cabinet integration while maintaining precision and low electrical noise.

The controller features built-in thermal management via an Internal Blower / Built-in fan Cooling system, ensuring stable operation even under sustained high-load conditions. Connectivity is streamlined through a Serial interface RS 232-C Additional Interface alongside a 16 bit parallel Speed Command input and a standard 10V Speed Set-Point reference. The drive’s Interface Terminal X4, configured with 25 poles, consolidates control signals and power lines into a single pluggable unit, simplifying wiring and maintenance. To optimize safety and compliance, the design omits an Additional Bleeder and Additional Encoder Input, reducing component count and potential failure points.

Engineered for seamless integration into CNC spindles and automated machining centers, the RAC 2.2-200-460-D0S-W1 offers precise digital speed control and rapid response to feedback loops. Its robust construction and fan-cooled enclosure deliver high reliability in harsh industrial environments, minimizing downtime and maintenance. When paired with Rexroth Indramat control modules, this spindle drive controller enhances system-level diagnostics and predictive maintenance capabilities, ensuring long-term operational excellence.
