Product Description:

The DKC05.3-018-3-MGP-01VRS drive controller is produced by Bosch Rexroth Indramat and belongs to the DKC Drive Controllers series. In an automation cell, this controller receives position commands from a motion processor and modulates DC-bus energy to match the torque, speed, and direction requirements of a connected servo motor. As part of a closed-loop axis, the unit handles real-time current control, regenerative energy routing, and fault monitoring to keep tooling, conveyors, or indexing tables on target. This makes it suitable for applications that need coordinated motion, controlled acceleration, and repeatable response during frequent starts and stops.

Electrically, the device operates from a DC link held at 300 V, a level that allows rapid energy exchange between braking and accelerating axes. Rated motor output is supported by a continuous current capability of 18 A, while the upstream supply only needs to furnish a peak of 3.1 A because of the internal power stage topology. During steady-state motion, switching losses can reach 750 W, so the housing and cabinet airflow must remove this heat to avoid derating. The unit uses hardware design 3, which places the power semiconductors and control board in a compact arrangement suited to DIN-rail mounting and dense cabinet layouts.

Operation is permitted up to 40 °C ambient, so enclosure ventilation must keep internal temperatures within that limit during normal duty. The unit has a mass of 2.1 kg, which supports mounting on lighter panels without adding much mechanical load. As an EcoDrive variant, it includes energy-saving functions that coordinate braking energy across multiple axes. Control flexibility comes from the Multi interface, general purpose control class and interface option 05, which provide additional fieldbus and I/O channels for packaging, material-handling, and assembly machines. These connections let the controller adapt to different machine architectures without changing its core drive behavior.
