RAC 3.5-150-460-D0D-W1-220

The Bosch Rexroth Indramat RAC 3.5-150-460-D0D-W1-220 from the RAC Spindle Drive Controllers series is a high-performance AC Main Spindle Drive Controller designed for versatile machining applications. It accepts 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 to meet demanding spindle requirements. Control electronics operate on a separate Rated Connection for Control Electronics of AC 230 V / 50-60 Hz, ensuring clean power separation and reliable operation. Version 5 of the Series 3 controller integrates seamlessly into modern automation environments.

Equipped with an Internal Blower / Built-in fan cooling system, the RAC 3.5-150-460-D0D-W1-220 maintains optimal thermal stability under continuous load. The unit provides a Digital (16 bit parallel) Speed Command and a dedicated Digital position set-point (16 bit parallel) Additional Interface for precise motion control. Connection is simplified via the Interface Terminal X4, 25 poles, while the absence of an Additional Encoder Input and Additional Bleeder reduces complexity and potential failure points. Robust internal design and isolation features uphold performance in harsh industrial climates.

This controller’s compact footprint and standardized interface architecture make retrofit and new-machine integration straightforward. Its modular construction and clear specification of Device Type and electrical ratings streamline commissioning and diagnostics. The RAC 3.5-150-460-D0D-W1-220 is an optimal choice for high-speed spindles, offering precise control, reliable cooling, and flexible interconnectivity.
