Product Description:
Bosch Rexroth Indramat manufactures the DKR05.2-W700N-BE12-01-B1NN-FW as part of the DKR Drive Controllers series. The device is a digital intelligent AC drive controller that converts line power into regulated three-phase output for high-power servo and induction motors in industrial automation cells. By delivering precise torque and speed commands, it coordinates multi-axis motion in presses, machining centers, and material-handling gantries while simplifying cabinet integration through its enclosed chassis. This type of controller is suited to applications where large motors must move heavy loads while remaining synchronized with the rest of the machine.
The controller is in line series 05, uses design version 2, and works with function module version 01, giving it a standardized configuration inside large automation cabinets. Communication with PLCs is provided by the SERCOS interface, allowing deterministic setpoint exchange and diagnostic reporting. This communication method supports coordinated motion control without relying on conventional analog command signals. Thermal management is handled by a built-in air blower that forces air through the heat sink. Under continuous duty, the unit can supply a nominal output of 700 A, driving motors up to 245 kW at 400 V. During this service, it dissipates 9.5 kW of heat, so the cabinet layout must provide sufficient airflow around the mounting frame.
The power section operates on a rigid DC bus and is supplied without a brake chopper, so braking energy must be handled by external devices during dynamic stops. This arrangement is used in systems that direct regenerated energy to external braking hardware or a common supply section. Motion feedback from each axis is returned through digital servo and resolver feedback, allowing the drive to work with both high-resolution encoders and resolver transducers. The cabinet is finished in light gray sheet steel, uses a lock that accepts a 3 mm two-way key, and is delivered without a door main switch. The unit has a mass of 650 kg, so the supporting structure must be sized for a substantial static load.
