Product Description:
The DKR03.1-W200N-BE24-01 is a drive controller built by Bosch Rexroth Indramat and positioned within the DKR Drive Controllers series. As a modular axis inverter, it supplies regulated power to synchronously or asynchronously controlled motors, coordinating motion profiles inside automated machining centres and material-handling lines. Its task is to process set-point data from a host automation system and convert that data into controlled motor currents, thereby closing the electrical and mechanical loop between a higher-level PLC and the mechanical load.
Communication with the control network takes place through a SERCOS interface, so cyclic position and diagnostics telegrams are exchanged over a fibre-optic ring. Thermal energy from the power section is moved out by a built-in blower, allowing full current delivery without reliance on cabinet ventilation. The power stage uses a rigid DC bus architecture that operates without a bleeder or brake chopper; excess kinetic energy must therefore be dissipated by the connected motor or an external resistor. Rotor position data can be interpreted by the controller’s dual-channel feedback electronics, which accept digital servo and resolver feedback in parallel, permitting mixed-sensor installations. Finally, this unit belongs to the 03 line, meaning its component geometry and firmware base align with third-generation DKR hardware.
Additional identification values refine compatibility during commissioning. Design status 1 confirms the mechanical layout and terminal assignment used by current production models, while function version 01 identifies the software feature set expected by the matching machine program. These codes help maintenance teams load the correct parameter set when swapping units. Manufactured by Bosch Rexroth Indramat, the controller inherits the company’s common diagnostic LED structure and keypad menu logic, streamlining operator training across different axes. Within the DKR Drive Controllers family, the device offers a consistent drive solution for medium-power spindles or servo axes that depend on tightly coordinated multi-axis motion.
