Product Description

Bosch Rexroth provides worldwide services in the manufacturing and maintenance of different industrial automation equipment. The company’s products such as drive controllers, servo motors, and converters are widely used in the international market.

The DKR04.1-W300E-BT49-01-FW model is designed to control electrical motors and monitor their operations. The model is specially used in printing machines and NC machine tools due to its broad speed range with extreme precision and continuous power delivery. The drive controller can take connection directly from the 3 × 400 ~ 480V main power supply. The model is equipped with an integrated mains contactor and an emergency stop shutdown device in case of any circuit failure. The drive controller comes with a SERCOS interface for high-speed real-time communication between control and motion device. The total height, width, and depth of the model are 1080 mm, 571 mm, and 370 mm. The minimum distance of 80 mm should be maintained at the top and bottom of the device. The model delivers the maximum power of 125 kW while operating at the peak current of 282 A under the ambient temperature range of +5 to +45 degree Celsius.

The model DKR04.1-W300E-BT49-01-FW comes with an external bleeder resistor which dissipates the continuous power of 3 kW and 200 kW of peak power. The auxiliary brake resistor is equipped with a 1.8 Ohm resistor which provides the maximum braking energy of 720 kWs. The driver controller and external bleeder resistor are protected by IP20 protection class and they can be installed at the maximum altitude of 1000 meters above sea level with the maximum bearable temperature range of +55 degree Celsius. The basic unit of the model is DKR04.1-W300E-B and the function numeric code of this model is 49 with 01 version function numeric code. The 4/8 kHz drive installed in the model can deliver the continuous power of 93/66 kW at the driven shaft of the motor while operating at the continuous current of 210/150 A. The air-type cooling method is used in this model. This unit can be shipped globally with a one-year warranty period from Wake Industrial.
