The RAC Spindle Drive Controller Series provides intelligent, digital control for INDRAMAT 2AD main spindle motors and 1MB frameless spindle motors with a continuous output shaft power of 10 to 30 kW. This drive series offers high-stiffness and constant power over a broad speed range, making it suitable for applications that require precise control. With high-resolution feedback, the RAC series enables the operation of the spindle as a servo-axis, allowing for accurate control even at low speeds. Additionally, the RAC series acknowledges rotor position, enabling precise control over the spindle's position and movement.
