The Bosch Rexroth R911256096 (RAC 3.5-150-460-API-Z1-220) is an AC main spindle drive controller designed for use in demanding motion control applications. It supports rated connection voltages of 3 x AC 400 V at 50 Hz (±15%) or 3 x AC 460 V, with control electronics rated at AC 230 V, 50-60 Hz. The unit delivers a rated current of 150 A and incorporates an integrated emergency-stop and main contactor system. It includes an additional bleeder, incremental encoder output, and an additional encoder input for spindle feedback. High-resolution INDRAMAT encoder support enables rotor position recognition up to 1/4,000,000th resolution. Cooling is provided by an internal blower or built-in fan. The drive accepts analogue speed commands of ±10 V and is equipped with an X4, 9-pole interface terminal. Mounting kit with flanges and screws is included; hose cooling accessories are not included.
