RAC 3.5-150-460-D00-Z1-220

The Bosch Rexroth Indramat RAC 3.5-150-460-D00-Z1-220 from the RAC Spindle Drive Controllers series is a high-performance AC Main Spindle Drive Controller designed for demanding CNC and machining applications. It operates on a Rated Connection Voltage of 3 x AC 400 V, 50 Hz, ±15% or 3 x AC 460 V and delivers a continuous Rated Current of 150 A, ensuring robust torque output. The controller accepts a Speed Set-Point of 10V for precise analog speed adjustments and features a 25-pole X4 Interface Terminal for streamlined field wiring. Integrated intelligence and a compact footprint simplify cabinet integration and reduce overall system complexity.

Performance flexibility is achieved with a Digital (16 bit parallel) Speed Command input, enabling high-resolution velocity profiling. Control electronics run on a Rated Connection for Control Electronics of AC 230 V / 50-60 Hz, while built-in Internal Blower / Built-in Fan cooling maintains optimal thermal conditions. The unit includes an Additional Bleeder circuit for safe discharge of DC-link capacitors and can be deployed without an Additional Encoder Input for standard setups. Firmware Version 5 support offers advanced parameterization and diagnostic capabilities out of the box.

With its simple mounting and standardized series design Series 3, the RAC 3.5 spindle drive controller delivers scalable performance across multi-axis installations. Its rugged construction, intelligent cooling strategy, and comprehensive terminal interfaces ensure reliable operation in industrial environments. Together with Bosch Rexroth Indramat’s application support and global service network, this drive controller provides an optimal balance of precision, power density, and maintainability.
