The R911266572 (RAC 3.5-200-460-LP0-W1-220) is a microprocessor-controlled AC main spindle drive controller designed by Bosch Rexroth. It operates with a rated connection voltage of 3 x AC 400 V, 50 Hz, ±15% or 3 x AC 460 V, and a rated current of 200 A. The device is equipped with an internal blower for cooling and incorporates plug-in terminals for monitor and readiness contact, as well as main contactor control and a motor NTC-resistor. The controller is compatible with both grounded and ungrounded three-phase supply networks, provided connector voltage matches the main voltage. It supports CNC, power, and feedback connections, and features an additional encoder input for spindle feedback using a high-resolution INDRAMAT encoder. The programming module stores software parameters and a type plate provides identification data. Peak controller output is 55 kW, and the unit weighs 49 kg. The interface terminal includes X4 optical waveguides and speed command via the SERCOS interface.
