Product Description:

The DKR03.1-W200N-BE23-01-FW is a drive controller built by Bosch Rexroth Indramat for multi-axis automation in machining centers, printing presses, and material-handling systems. As part of the DKR Drive Controllers series, it converts line power into a regulated DC link and delivers pulse-width-modulated output to synchronous or induction motors. This arrangement lets the controller regulate speed and torque with the timing needed for coordinated axis motion across multiple machine sections. In equipment that depends on synchronized movement, it supports stable operation during acceleration, constant-speed running, and controlled deceleration.

The power section has no bleeder resistor, so regenerative energy must be handled by external components during deceleration or overhauling loads. Communication with the host control uses the SERCOS interface, allowing deterministic transfer of setpoints and diagnostic data over a fiber-optic ring. Thermal management relies on a built-in air blower, which moves cabinet air across the heat sinks and removes the need for ducted cooling water. For closed-loop operation, the unit accepts digital servo and resolver feedback, so it can operate with motors that provide either high-resolution encoder signals or analog resolver signals without a separate feedback converter. This gives the controller flexibility in systems where different motor feedback types are already in use.

The controller is released as design version 1, which identifies its mechanical layout and component set within the product line. It uses function numeric version 01, and it belongs to line 03. These identifiers are used to match the controller with compatible system components and the expected control feature set. The controller type is DKR, which places it within the corresponding drive family. This coding keeps the product designation consistent across related controller modules.
