RAC 2.3-200-380-AY0-W1

The Bosch Rexroth Indramat RAC 2.3-200-380-AY0-W1 from the RAC Spindle Drive Controllers series is a robust AC main spindle drive controller designed for high-performance industrial applications. With a rated connection voltage of 3 x AC 400 V, 50-60Hz and a rated current of 200 A, this device delivers powerful and reliable drive control for demanding spindle operations. Key features include an additional encoder input for enhanced motion feedback and an integrated internal blower / built-in fan cooling system, ensuring continuous operation under heavy loads and preventing overheating. This controller’s primary function is to provide precise and stable power delivery to the main spindle, enabling accurate rotational speed regulation and seamless integration into CNC machinery.

The RAC 2.3-200-380-AY0-W1 excels through its advanced technical specifications. Designed as an AC Main Spindle Drive Controller, it supports analogue (+/- 10 V) speed command signals and accommodates an incremental encoder (JL) for feedback with lead spindle precision. The inclusion of an additional encoder and synchronous input allows for dual-feedback configurations, enhancing dynamic response and positional accuracy. Its interface terminal X4, 9 poles ensures straightforward wiring and compatibility with existing control systems. The controller is built in series 2, version 3, reflecting refinements in firmware and hardware for improved reliability and streamlined performance.

Beyond raw performance metrics, this spindle drive controller offers exceptional compatibility and efficiency. Its cooling system, featuring an internal blower, reduces maintenance by simplifying airflow management and eliminating external fans. The absence of an additional bleeder simplifies the power circuit while maintaining safe discharge characteristics. Designed for seamless integration, the device supports standard 3 x 400 V networks and common encoder types, reducing installation complexity. In industrial settings, the RAC 2.3-200-380-AY0-W1 delivers enhanced spindle stability, minimized downtime, and precise speed control, making it an ideal solution for high-speed machining, milling, and grinding applications where reliability and accuracy are paramount.
