The R911256872 (RAC 3.5-200-460-L00-W1-220) is a main spindle drive controller from the RAC series, produced by Bosch Rexroth Indramat, with the capability to support C-axis operations. This high-precision device is designed to control the 1MB and 2AD motors with a continuous power of 35kW, having a continuous current rating of 92A. The controller supports three feedback interfaces and presents an interactive control panel comprising a keypad designed for easy parameter input during its installation.
Created to meet DIN VDE 0160 specifications, the R911256872 (RAC 3.5-200-460-L00-W1-220) uses a SERCOS interface for real-time control and monitoring of speed, torque, and position set-points of CNC units. Operating in temperatures of up to 55 degrees Celsius, the unit also complies with DIN 40 040 rating of Class F for humidity, barring condensation on its surface during operation. The product's housing also assures a layer of protection with a rating of IP 54, ensuring resistance to any objects with over 50mm diameter. The R911256872 (RAC 3.5-200-460-L00-W1-220) should always function in a vertical position with a keen observance to keep the heatsink and air shafts clean to avoid overheating. The drive functions through three kinds of electrical connections and does not accommodate additional encoder input or interfaces.
