Product Description:
The DKC05.3-200-7-FW is a modular drive controller manufactured by Bosch Rexroth Indramat within the DKC Drive Controllers series. Intended for use with the EcoDrive motion platform, the unit governs torque, velocity, and position loops for synchronous and asynchronous motors in automated machinery. By linking the power stage and control electronics in a compact frame, the controller simplifies cabinet layouts and provides a standardized interface between industrial PLCs and distributed servo axes for conveyor, positioning, and transfer applications.
Internally, the controller supports a DC link held at 700 V; this voltage is the primary energy reservoir that feeds the IGBT output stage and sets the insulation and clearance requirements for connected components. The output stage is dimensioned for a continuous rated current of 200 A, allowing it to drive high-torque motors without reaching current limits during normal operation. On the supply side, the unit can draw up to 38 A, so upstream circuit protection and cable sizing must accommodate that demand. When delivering nominal current, the module converts switching losses into 960 W of heat, so enclosure airflow or external heat sinks are required to keep semiconductor junction temperatures within permissible limits. Reliable operation is permitted up to 45 °C, enabling installation in standard factory panels without additional chillers.
The unit uses Design 3, which corresponds to the third mechanical revision and aligns mounting points with later EcoDrive accessories. Communication flexibility comes from Interface Option 05, a slot that accepts fieldbus cards for SERCOS or analog command signals used in coordinated multi-axis cells. This slot-based arrangement lets the same power section be adapted to different command interfaces without changing the main controller body. The controller is an EcoDrive module, so it fits within that drive platform and supports the related control architecture. A mass of 19.5 kg must be considered during cabinet layout, mounting support, and handling.
