The R911238571 (RAC 2.2-150-380-A0S-Z1) is an advanced spindle drive controller with an integrated closed position control loop for precise spindle positioning based on motor feedback. It can also operate the spindle as a servo-axis via high-resolution feedback, ensuring high precision even at very low speeds. Its sensor can detect the rotor's position with a maximum resolution of about 1/4000000 rotations. The controller's operating conditions rely on environmental factors such as ambient temperature, installation altitude, and permissible humidity, with the latter adhering to DIN 40 040 class F, stating an average relative humidity of under 70%. The optimal operating temperature ranges from 5℃ to 45℃, though it can endure up to 55℃. It can be installed up to 1000m above sea level. The controller manages excess heat through air slots and heat sinks, with external cooling provided if necessary. A built-in bleeder discharges electric charges stored in the power supply's filter capacitor for added safety during shutdown.
