DKR Drive Controllers
The DKR05.2-W700N-BE12-01-B1NN-FW is a drive controller built by Bosch Rexroth Indramat for the DKR Drive Controllers series. Within the naming structure it belongs to line series 05, carries design version 2, and is identified with function numeric version 01. The unit is installed in multi-axis machining centers and presses where it supplies regulated DC power and closed-loop motion commands to high-torque servomotors. By coordinating power conversion, communication, and fault monitoring, it forms the link between the factory mains and the machine tool control network.
Electrical throughput is defined by a nominal current of 700 A, which is identical to its current rating and permits connection of motors up to 245 kW at 400 V. Those power levels generate internal losses; the controller therefore dissipates 9.5 kW as heat and relies on an Air (built-in blower) system to move that heat out of the cabinet. Axis and PLC commands travel over a SERCOS interface, allowing deterministic fiber-optic communication and synchronized update cycles. Together these parameters establish the maximum mechanical output, thermal load, and real-time bandwidth available to the connected motion axes.
The power section operates on a rigid DC bus configured with No bleeder, Without brake chopper, and a rigid DC bus, so regenerative energy must be managed by the machine rather than internal braking resistors. Position verification uses Digital servo and resolver feedback channels to match the commanded profile with actual rotor position at high current levels. The housing is finished in Light gray enamel and weighs 650 kg, factors that influence lifting, cabinet layout, and thermal reflection. A lock for a 3 mm two-way key secures the cabinet door, and the design is shipped without a door main switch so the machine builder provides the disconnect.
