RAC 3.1-100-460-A0I-W1-220
RAC Spindle Drive Controllers
RAC 3.1-100-460-A0I-W1-220, manufactured by Bosch Rexroth Indramat, is part of the RAC Spindle Drive Controllers series designed for precision spindle regulation in demanding industrial automation environments. This Device Type delivers a robust Rated Current of 100 A at a Rated Connection Voltage of 3 x AC 400 V, 50 Hz, +/-15% or 3 x AC 460 V, ensuring consistent torque output under variable mains conditions. Its compact footprint combines with a Controller weight of 49 kg to streamline installation in space-constrained control cabinets. Native Incremental encoder output and RS-232C Serial interface support seamless integration with feedback systems and host controllers.
Engineered for reliability, the drive features an Internal Blower / Built-in fan cooling system to maintain optimal thermal performance across an Ambient operating temperature range of 5 to 45°C. Control electronics operate from a separate Rated Connection for Control Electronics of AC 230 V / 50-60 Hz, consuming just 200 VA of control power. Speed is commanded via an Analogue (+/- 10 V) input, while the Interface Terminal X4 (9 poles) provides secure, low-noise signal routing. The unit meets IP10 per EN 60529 protection standards and withstands -30 to +85°C storage temperatures, with humidity resilience rated to F per DIN 40040 (≤70% RH, no condensation).
Integration into machine tool and spindle systems is simplified by its standardized interfaces and compact design, reducing cabinet wiring complexity. The rugged protection category and controlled cooling scheme enhance reliability for continuous operation in fabrication, milling, and turning centers. As part of the Bosch Rexroth Indramat ecosystem, the RAC 3.1-100-460-A0I-W1-220 offers scalable performance and predictable maintenance schedules, maximizing uptime in precision-driven manufacturing lines.
