Product Description:

The DKR03.1-W200N-BE48-01-FW is a drive controller produced by Bosch Rexroth Indramat for the DKR Drive Controllers series. The module converts setpoint data from higher-level motion systems into controlled current and voltage for servo axes, making it suitable for high-speed machine tools, packaging lines, and material-handling gantries. By integrating power electronics, signal processing, and system diagnostics in one chassis, the unit supports closed-loop torque, speed, and position control without requiring separate external hardware for each function. It can manage rapid axis response during acceleration, contouring, and load changes where stable current regulation is important to motion quality. This arrangement helps keep cabinet layouts compact while supporting coordinated multi-axis automation.

The primary communication path is the SERCOS interface, a real-time fiber-optic link that carries synchronized position, velocity, and diagnostic data between the drives and the central controller. Internal heat is removed by a built-in air blower, which channels air across the heat sink so the module can operate in enclosed cabinets without external ducts. The drive uses a rigid DC bus topology that returns regenerated energy to the supply instead of dissipating it as heat. Motion feedback flexibility is provided by digital servo and resolver feedback, allowing the controller to process absolute or incremental position data from compatible servo motors. This combination supports both resolver-based motor systems and digital feedback devices within the same control platform.

This unit belongs to Line 03, is assembled as Design version 1, and carries Function version 01. These codes indicate the controller layout and parameter structure used by this unit, which helps keep the product matched to the correct control configuration. Because the power stage is shipped without a brake chopper, braking energy must be handled by the common DC link or by external supply modules. In rack-based systems, this setup is often used with shared energy management across several connected axes.
