The Bosch Rexroth Indramat R911256109 (RAC 3.5-150-460-L00-Z1-220) is a RAC series main spindle drive controller, custom designed for the digital modulation of asynchronous spindle motors with power ratings ranging from 10 to 30 kilowatts. This product, designed as series 3, type 5, boasts an impressive current rating of 150 Amps. It operates optimally with a three-phase 380 to 460 Volts AC main power supply and a 220 Volts AC input for the control electronics. The controller possesses an integrated emergency stop circuit and mains contactor and utilizes a built-in bleeder to facilitate braking when the power supply fails. The power regenerated during braking is then effectively redirected to the three-phase mains power supply network.
The R911256109 (RAC 3.5-150-460-L00-Z1-220) stands out with its advanced features such as a SERCOS interface for speed set-point determination and an inbuilt cooling fan to assist air convection cooling. The controller allows for air conditioning from either its interior or exterior and requires a minimum clearance of 160 millimeters when mounted vertically for ideal air flow. Operationally, the ambient temperature should range between 5 to 45 degrees Celsius. A specially provided heatsink deals with any excess heat generated by the power electronics. The R911256109 (RAC 3.5-150-460-L00-Z1-220) weighs approximately 49 kilograms and does not support additional encoder input or interface.
