The Bosch Rexroth Indramat DKR02.1-W300N-BE43-01-FW is a digital intelligent AC drive controller from the DKR Drive Controllers series. It features a SERCOS command interface, handles continuous currents of 141 A at 4 kHz, and delivers approximately 55 kW of continuous power. The controller is cooled by a built-in blower and weighs about 104 kilograms.
Internal Product Review
The DKR02.1-W300N-BE43-01-FW is a digital intelligent AC drive controller with a SERCOS interface and digital servo/resolver feedback. Air cooling from the built-in blower and continuous power of about 55 kW give the unit strong thermal stability and a capable operating profile. A peak current of 212 A stands out as a key performance advantage.

Product Description:
The DKR02.1-W300N-BE43-01-FW drive belongs to the DKR Drive Controllers series from Bosch Rexroth Indramat. As a digital intelligent AC drive controller, it regulates high-power servo and spindle motors used in machining centers, printing lines, and automated assembly systems. The unit receives feedback from digital servo encoders or resolvers and supplies variable three-phase power to match commanded motion profiles.
The controller’s power section is designed for a mains range of 3 x AC 400 to 480 V ± 10%, and its internal electronics are energized by a logic supply of AC 230 V ± 10%. At the default 4 kHz pulse frequency, the inverter can deliver a continuous current of 141 A, which corresponds to roughly 55 kW of sustained mechanical output from the connected motor system. For acceleration or transient load events, the current reserve climbs to 212 A, allowing short bursts of torque without violating thermal limits. Motion commands and diagnostic data are exchanged through the SERCOS interface, and an integrated blower channels air through the heat sink to stabilize semiconductor temperatures during full-load operation.
Total losses removed by the cooling circuit reach 1800 W, so panel ventilation must accommodate this heat while the DC bus design omits a brake chopper or external bleeder. The absence of a dynamic brake is possible because the DC link can accept energy returned during regenerative deceleration. Cooling is provided by a built-in air blower, and the overall mass is approximately 104 kg, which is suitable for direct cabinet mounting with standard lifting equipment. The controller has a current rating of 300 A and is in Line 02 with design version 1. Function module 43, revision 01, provides application-specific logic while still accepting both digital servo and resolver feedback.
