RAC3.5-150-460-A01-W1

The Bosch Rexroth Indramat RAC3.5-150-460-A01-W1 drive controller from the RAC Spindle Drive Controllers series is a high-performance solution engineered for demanding industrial applications. As an AC Main Spindle Drive Controller, it delivers precise torque control and dynamic response for milling and turning centers. Built with a robust IP 10 protection category, the module ensures baseline defense against debris in factory environments. Its streamlined form factor weighs a manageable 49 kg, simplifying cabinet layout and handling during installation.

Designed for continuous heavy-duty operation, this unit sustains a Continuous controller current of 150 A and produces a Continuous controller output of 35 kW, while accommodating peaks up to 40 kW of Peak controller output. The controller accepts a Rated supply voltage of 3 x AC 380 - 460V, ±10%, 50 - 60Hz and an auxiliary Control voltage of AC 230V, ±10%, 50 - 60Hz for drive logic and safety circuits. An integrated cooling system with built-in fan maintains optimal thermal regulation across an Ambient temperature range of 5 to 45 centigrade, protecting sensitive power semiconductors. Regenerative braking is managed internally, with a dedicated Regeneration output of 27 kW, enabling energy recovery and reducing external resistor requirements.

Engineers benefit from the controller’s seamless integration into Bosch Rexroth automation networks and straightforward mounting interfaces. The combination of high overload capacity, reliable fan-assisted Cooling, and robust Protection category makes the RAC3.5-150-460-A01-W1 exceptionally dependable in continuous production. Ideal for spindles in CNC machining centers, this controller enhances operational uptime and simplifies system diagnostics for maintenance teams.
