Product Description:
The RAC3.1-150-460-A0I-W1 is a premier spindle drive controller by Bosch Rexroth Indramat, purpose-built for driving main spindle motors with unmatched precision and robustness. This model seamlessly integrates with 2AD asynchronous and 1MB frameless spindle motors, standing out with a continuous power provision of up to 35 kW and capable of surging to a peak of 55 kW for intensive operations. The direct connection to a three-phase supply ranging from 380 to 460 volts, complemented by built-in mains contactors and emergency-stop circuits, assures a reliable and efficient energy recovery during braking, even in an emergency halt. Exceptionally, this drive controller supports spindle positioning and C-axis operations with high-resolution feedback, enabling precise control down to a fraction of a revolution. Whether in C-axis applications that demand extreme precision or in challenging positioning tasks, the RAC3 series demonstrates remarkable versatility and accuracy. Notably, the RAC3.1-150-460-A0I-W1 offers various cooling options, including integrated fan and hose cooling capabilities, ensuring optimal thermal management for a broad ambient temperature range, especially within the standard operating conditions from +5 to +45 °C. Its design facilitates ease of installation, allowing for cooling with either internal or external control cabinet air, which can be structurally adjusted if necessary. The controller’s compatibility with various interfaces, including analogue, digital, and SERCOS interfaces, underpins its capacity to adapt to a multitude of industrial scenarios and complex applications. Furthermore, its robust construction is reflected in its capability to operate up to an altitude of 1000 meters without de-rating, which, along with its IP 10 protection category, underscores its suitability for diverse operational environments. This blend of features makes the RAC3.1-150-460-A0I-W1 an essential component for contemporary industrial automation solutions where reliability, adaptability, and precision are non-negotiable.
