R911256096
The R911256096 (RAC 3.5-150-460-API-Z1-220), produced by Bosch Rexroth Indramat, is a main spindle drive controller with an integrated emergency-stop switch and main contactors. This industrial component has a current rating of 150A with control electronics voltage rating of AC 220 V/50 to 60 Hz, while the power electronics component comprises 3 x AC 380 to 460V with the same frequency range. Unique to this product, the recovered energy during the braking phase gets returned into the triphasic supply network. Moreover, this drive controller provides an analogue speed set-point of +/- 10 volts and an additional interface for incremental encoder output. Notably, the drive recognizes rotor position at an impressive resolution of 1/4 000 000th.
The R911256096 (RAC 3.5-150-460-API-Z1-220), remarkably versatile, fits into standard CNC controls, offering high stiffness and a broad speed range. Equipped with high-resolution feedback, this drive controller greatly illuminates rotor location spotting. Cooling is maintained by a built-in fan, and air can be circulated inside or outside as per the requirement. The product comes with a mechanical accessories kit containing all necessary flanges and screws for mounting, though hose cooling requires a separate purchase. All these make the Indramat R911256096 (RAC 3.5-150-460-API-Z1-220) an essential component for industrial applications.
