Product Description:
The DKR02.1-W300N-BE11-02-FW is a drive controller manufactured by Bosch Rexroth Indramat and supplied within the DKR Drive Controllers series. The module accepts three-phase power, rectifies the supply internally, and delivers adjustable output to synchronous and asynchronous servo motors. Through closed-loop current and velocity control, it supports precise positioning, coordinated multi-axis motion, and rapid acceleration cycles in machine tools, transfer lines, and forming equipment. Its electronics monitor thermal limits and fault states so the higher-level control system can react to abnormal conditions before they interrupt normal machine operation.
Signal exchange is handled through the SERCOS interface, which provides deterministic cyclic data for motion commands, status exchange, and parameter access. Internal cooling is provided by a built-in air blower that moves air across the heat sinks, helping the controller sustain a continuous current of 300 A during demanding operation. Position and speed are processed through digital servo and resolver feedback, allowing the controller to work with encoder-based and resolver-based motor feedback systems without changing the core control function. The DC link is configured without a brake chopper, so braking energy must be handled by an external resorption or regeneration solution when decelerating high-inertia loads.
The drive is identified as design version 1 and line series 02. These identifiers help distinguish the unit within the product range and support correct matching with related modules, fiber-optic components, and accessory braking hardware. The controller is intended for high-power motion applications that require stable current regulation, predictable communication behavior, and controlled handling of regenerated energy during braking.
