Product Description:

Bosch Rexroth Indramat manufactures the DKC03.3-012-3-MGP-01VRS as part of the DKC Drive Controllers series. This unit functions as a closed-loop power stage that modulates voltage and current delivered to synchronous or induction servomotors, allowing speed, position, and torque regulation in assembly cells, packaging machines, and material-handling axes. By coordinating motor feedback with command signals from higher-level PLCs, the controller serves as the central actuation element of a drive train and converts control data into precisely metered three-phase output power. Its role in the axis is to keep commanded motion stable during acceleration, steady running, and load changes.

Electrical performance centers on a DC-bus nominal voltage of 300 V fed by the machine supply. Under nominal conditions, the device delivers a continuous phase current of 12 A, enabling mid-range motor frames to accelerate and hold load torque without derating. Inrush is limited, and the maximum input current peaks at 2.2 A, which helps keep upstream supply loading predictable during startup. Internal heat generated by switching losses remains manageable, with power dissipation fixed at 400 W during continuous current flow. Ambient operation is permitted up to 40 °C, so the controller can be installed in a standard control cabinet when the enclosure temperature stays within that limit.

The unit belongs to design level 3, which aligns its mechanical layout with other third-generation EcoDrive modules. Communication flexibility is expanded through interface option 03, allowing the controller to exchange process data over multiple bus protocols. The control type is Multi interface, general purpose, which supports broad integration across different machine control schemes. Installation weight is only 1.8 kg, so the controller is easy to handle during panel assembly and can be mounted in compact drive sections without placing much load on the enclosure structure. The compact form also helps when several axes are arranged side by side on a backplate or mounting rail.
