DKR03.1

The Bosch Rexroth Indramat DKR03.1 drive controller from the advanced DKR Drive Controllers series represents a high-performance solution for precise motor management and automation control. Designed in design version 1 and line series 03, this control unit offers a built-in blower cooling mode to maintain optimal operating temperatures. Key features include an integrated brake resistor for rapid deceleration, a robust control voltage power rating of 200 A, and a control voltage tolerance of 10% to ensure consistent performance under varying supply conditions. The compatibility with 1MB series drives, AC spindles, and LSF motors makes the DKR03.1 suitable for a wide range of industrial applications requiring reliable motion control.

In terms of technical specifications, the DKR03.1 operates on a three-phase power supply of 3x AC 400 to 480 V at a main frequency of 50/60 Hz. Its driver controller power voltage spans from 0 to 300 V, providing versatile voltage regulation for different motor types. The control unit’s architecture accommodates a product series reference of DKR and delivers a control voltage tolerance of 10% to safeguard against voltage fluctuations. A built-in blower provides effective cooling, ensuring continuous operation without the need for external fans. Additionally, the controller’s specification sheet highlights a brake resistor option that can be integrated to enhance deceleration performance and protect the system from overvoltage conditions during regenerative braking.

The DKR03.1 controller is compatible with 1MB drive modules, AC spindle motors, and LSF motor types, delivering seamless integration within existing Bosch Rexroth automation ecosystems. Its durable construction and built-in blower cooling mode enhance system reliability and longevity, while the optional brake resistor improves energy efficiency by dissipating regenerative energy. Weighing in at 49 kg for the controller and 50.7 kg with the accessories kit, this compact unit strikes an optimal balance between robust design and manageable footprint. Ideal for demanding industrial environments, the DKR03.1 drive controller provides precise speed regulation, efficient energy management, and scalable performance for modern manufacturing and process automation applications.
