Product Description:
The DKC03.3-004-3-MGP-01VRS is a compact EcoDrive controller built by Bosch Rexroth Indramat for the DKC Drive Controllers series. As a closed-loop power stage, the unit coordinates torque, speed, and position feedback between Indramat servo motors and higher-level PLCs. By converting rectified bus power into three-phase motor output and monitoring load conditions in real time, it serves as the central regulator in packaging lines, material handling stations, and other motion-critical machines. It also supports modular cabinet layouts in which multiple axes share a common DC bus and operate with short cycle times. This arrangement is useful on synchronized feeders, transfer units, and indexing axes that must respond quickly to changing commands.
The controller is supplied from a DC link held at 300 V. This bus voltage sets the peak inverter output and the insulation level required for connected components. Under continuous operation, the power section delivers a rated phase current of 4 A, while incoming mains draw is limited to a maximum of 1.1 A, allowing compact protective devices in multi-axis cabinets. Thermal loss reaches 100 W at that continuous current, so cabinet airflow must remove the heat during operation. Ambient temperature must stay at or below 40 °C to avoid thermal derating or over-temperature trips. Stable ventilation becomes especially important when nearby axes on the same bus accelerate and decelerate repeatedly.
The unit uses the multi-interface, general-purpose configuration in this Design 3 version. Revision level 01 aligns with Interface Option 03, so the drive can communicate through SERCOS rings or parallel command words without extra hardware. Even with these communication options, the enclosure weighs only 1.8 kg, allowing dense mounting and reducing panel loading. The shared DC bus architecture can pass regenerative energy between axes, which helps compact systems use available power more efficiently. Its light housing also suits machines where low cabinet mass and limited installation space are both important.
