RAC 2.3-200-380-API-W1

The RAC 2.3-200-380-API-W1, Bosch Rexroth Indramat, RAC Spindle Drive Controllers unit is an advanced AC main spindle drive controller designed for precision machining environments. It operates as a dedicated Device Type controller, offering smooth speed regulation and robust performance. With a compact footprint, it integrates seamlessly into existing control cabinets, simplifying retrofits and new installations alike. The drive series leverages the proven reliability of Bosch Rexroth Indramat components to deliver consistent, high-quality spindle motion.

Engineered for demanding applications, the controller accepts a Rated Connection Voltage of 3 x AC 400 V, 50-60Hz and provides continuous output at a Rated Current of 200 A. A built-in Cooling system featuring an Internal Blower / Built-in fan maintains optimal operating temperatures under full load. Speed feedback and control signals are handled through an Additional Interface offering an Incremental encoder output and an Additional Encoder Input for spindle feedback. The drive communicates via a Speed Command of Analogue (+/- 10 V) and interfaces through the Interface Terminal X4, 9 poles for reliable signal integrity. With no Additional Bleeder required, the unit minimizes component count and reduces maintenance points. The onboard high-resolution Encoder Type (INDRAMAT encoder (~)) ensures precise position and velocity monitoring.

Designed for straightforward integration, the RAC 2.3-200-380-API-W1 uses DIN-rail or panel mounting to fit diverse cabinet layouts and control architectures. Its modular Series 2, Version 3 hardware platform delivers long-term reliability and field serviceability, with plug-and-play encoder connections and fan access for rapid maintenance. Ideal for high-speed spindles in milling, grinding, and turning centers, this drive controller provides deterministic performance, reducing setup time and enhancing overall system uptime.
