Product Description

Bosch Rexroth provides worldwide services in the manufacturing and maintenance of brake resistors, drive controllers, and frequency converters for different automated processes in industries. The company’s main concern is customer satisfaction.

The RAC 2.3-250-460-D0I-W1 model can take connection directly from 3-phase AC 400~460 V power supply having 50/60 Hz of the operating frequency with ±15% tolerance. The main spindle drive controller is designed to operate at the rated current of 400 A while delivering continuous controller output of 65 kW at the motor’s output shaft. The model comes with a digital 16-bit parallel speed set-point for connection to the PLC controller and without any additional encoder input option. The main spindle drive controller is mainly used as a CNC main spindle controller and its additional incremental encoder output interface helps in controlling position during C-axis operation. The model comes without any additional bleeder resistor and produces the continuous regeneration output of 43 kW and peak bleeder output of 78 kW for maximum of 5 seconds.

The model RAC 2.3-250-460-D0I-W1 is protected by IP10 protection class with humidity category F according to DIN 40 040 which makes it suitable to work under humid conditions. The model can operate ideally between the temperature ranges of +5 to +45 ͦC without a reduction in drive data. The total weight of the controller is approximately 121 kg with a 3 kg weight of mounting frame and accessories. The model is delivered with a cooling system having a built-in fan which uses a control cabinet outside air for cooling purposes. The controller can deliver the peak output of 78 kW and provides intelligent digital control of 2AD asynchronous and 1MD frameless spindle motors with continuous power and extreme precision. This unit can be shipped globally with a one-year warranty period from Wake Industrial.
