RAC 3.5-200-460-A0I-Z1-220

RAC 3.5-200-460-A0I-Z1-220, Bosch Rexroth Indramat, RAC Spindle Drive Controllers deliver high-performance spindle control for demanding industrial machining centers. This AC Main Spindle Drive Controller from the RAC Spindle Drive Series provides flexible voltage compatibility and precise command response. Engineered for robust operation, it features an upgraded Version 5 hardware platform in the compact Series 3 package. Its integrated design simplifies installation while ensuring consistent performance under continuous load.

Optimized for heavy-duty spindles, the unit accepts a Rated Connection Voltage of 3 x AC 400 V, 50 Hz, +/-15% or 3 x AC 460 V, and supplies a continuous Rated Current of 200 A to the motor. The built-in Internal Blower / Built-in fan ensures efficient Cooling under sustained high-speed operation. Control electronics are powered by AC 230 V / 50-60 Hz through the dedicated Rated Connection for Control Electronics input. A standard Analogue (+/- 10 V) Speed Command interface delivers smooth setpoint transitions, while the Interface Terminal X4 (9 poles) supports secure wiring layouts. Optional modules include an Incremental encoder output for feedback and an Additional Bleeder circuit to ensure safe discharge, whereas the drive is supplied Without additional encoder input to accommodate third-party encoder systems.

Designed for seamless integration into CNC platforms, this drive controller supports modular expansions without footprint increases, enhancing system scalability. Its rugged construction and intelligent thermal management deliver high reliability and reduced downtime in continuous-operation environments. Ideal for milling, grinding, and turning applications, the RAC 3.5-200-460-A0I-Z1-220 maximizes spindle responsiveness and torque stability, driving productivity in advanced manufacturing lines.
