Product Description:
The DKC04.3-040-7-FW is a drive controller produced by Bosch Rexroth Indramat for the DKC Drive Controllers series. It is used in industrial automation to regulate torque, speed, and position of connected synchronous or induction motors, allowing coordinated motion in packaging lines, material-handling cells, and general machinery. By converting fixed-frequency mains power into a variable three-phase output, the unit serves as the central power stage between the plant supply network and the motor windings. This arrangement allows the controller to support controlled acceleration, steady-speed operation, and responsive changes in load conditions.
The controller’s intermediate circuit operates at a DC-bus nominal voltage of 700 V, providing the energy buffer that the inverter section draws on during acceleration or regeneration. A continuous phase output of 40 A is the maximum current the unit can supply without derating, while the cabinet feed must accommodate a maximum input current of 16 A under peak loading. Thermal management is based on a power dissipation of 180 W at rated current, so this heat must be removed by panel ventilation or a heat sink to maintain internal component limits. Safe operation without derating is permitted up to an ambient temperature of 45 °C, so enclosure airflow must keep the controller below this level. These operating values should also be matched to the motor and panel layout so the drive can run within its intended duty range.
The unit uses Interface Option 04, which provides a specific communication and feedback connector set. It also carries Design code 3, indicating the third hardware revision within the series. The enclosure mass of 5.7 kg affects mounting support and vibration loading when the controller is installed in compact panels. Classified as an EcoDrive product type, the controller follows the EcoDrive platform structure used across related DKC models. This helps keep setup and parameter handling consistent when the drive is used with other products in the same platform.
