RAC 2.1-150-460-A0I-W1-220
RAC Spindle Drive Controllers
The RAC 2.1-150-460-A0I-W1-220, Bosch Rexroth Indramat, RAC Spindle Drive Controllers unit delivers precise spindle control in high-demand industrial automation. Engineered as a compact yet powerful solution, this controller integrates seamlessly with production lines requiring rapid, repeatable positioning. Its robust design supports continuous operation under fluctuating line voltages, assuring consistent performance in metalworking, milling, and drilling applications. Built to meet stringent factory standards, the RAC 2.1-150-460-A0I-W1-220 balances power density with ease of service.
Featuring a Rated Connection Voltage of **3 x AC 400 V, 50 Hz, +/–15%** or **3 x AC 460 V**, the drive supports a Rated Current of **150 A** to power demanding spindle motors. The Device Type is an **AC Main Spindle Drive Controller** with an integrated Cooling system comprising an **Internal Blower / Built-in fan** for efficient thermal management. Control electronics operate from a separate Rated Connection for Control Electronics of **AC 230 V / 50-60 Hz**. For precise motion feedback, an Encoder Input of **Incremental** type is provided alongside an Additional Interface offering **Incremental encoder output**. Speed set-points are applied via an analog Speed Command of **+/–10 V**, while digital reference is supported through a **Digital Position Set-Point** input. The unit communicates status and diagnostics over a **Serial Interface (RS-232C)** and connects to peripheral sensors via a **9-pole Interface Terminal (X4)**.
Designed for straightforward integration, the RAC controller’s compact footprint and standard interfaces simplify retrofits and new installations. Its built-in fan and conformal connectors enhance reliability in harsh environments, reducing maintenance intervals. Ideal for CNC lathes, grinding centers, and automated milling cells, the RAC 2.1-150-460-A0I-W1-220 ensures tight speed regulation and rapid response for superior machining accuracy.
