R911261089
The R911261089 (RAC 2.3-200-380-L00-W1) is a spindle drive controller designed by Bosch Rexroth Indramat, belonging to their RAC series. It operates with an input rating of 400 Volts AC and accepts a three-phase input at frequencies ranging from 50 to 60 Hertz. With a current rating of 200 Amps, this controller is suitable for the control of the 2AD series spindle motors, offering power output up to 52 kilowatts. The controller's optimal performance is maintained in an ambient temperature range of 5 to 45 degrees Celsius, reducing its output to 80% when the temperature reaches 55 degrees Celsius. When not in use, the controller can withstand temperatures between -30 to 85 degrees Celsius.
The R911261089 (RAC 2.3-200-380-L00-W1) controller includes an integrated cooling fan, drawing in air from outside its control cabinet. Modifications may be required if the application's cooling method differs. Additionally, it can perform up to 1000 meters above sea level without a reduction in output. The controller is encased in an IP10 rated housing per EN 60 529 standards and does not incorporate an additional bleeder, interface, or encoder input. Equipped with a SERCOS interface for speed set-point, the controller is configured via the AC programming module provided with each new unit.
