Product Description:
The DKC03.3-018-3-MGP-01VRS drive controller is produced by Bosch Rexroth Indramat as part of the DKC Drive Controllers series. The unit acts as the power and control stage between the plant’s supply network and synchronous or induction servo motors used in automated machinery. By modulating DC-bus energy and responding to position commands, it enables coordinated motion, speed regulation, and torque control required for packaging, material-handling, and assembly lines. This operating role makes the controller suitable for axes that must accelerate, decelerate, and hold stable motion under changing load conditions.
The controller’s continuous output capability is 18 A, indicating the maximum armature current it can supply without derating. That current is drawn from an internal DC link stabilized at 300 V, so the connected drive receives a fixed intermediate voltage regardless of line fluctuations. On the line side, the module will draw up to 3.1 A, a figure used for fuse sizing and cable selection for the supply feeder. When delivering its rated current, thermal losses amount to 750 W; this heat must be removed by cabinet ventilation to keep internal components within safe operating limits. Stable bus voltage also helps the controller maintain predictable response during repeated starts, stops, and load changes. The installed multi-interface, general-purpose software manages fieldbus traffic, diagnostic reporting, and parameter storage for various motor types.
The hardware is classified as Design 3, paired with software version 01 for this model. System layout is simplified by the compact mass of 2.1 kg, allowing dense mounting in multi-axis racks. Environmental suitability extends to a maximum ambient of 40 °C, after which additional cooling is advised. Communication flexibility comes from Interface Option 03, which provides the multiprotocol channel used by the controller. As an EcoDrive, the module also supports energy return to the DC bus when the connected axis brakes. This can reduce wasted braking energy during deceleration on systems with several coordinated axes.
