Product Description:

The DKC14.3-200-7-FW drive controller is manufactured by Bosch Rexroth Indramat within the DKC Drive Controllers series. As part of the EcoDrive platform, it converts the rectified DC bus supply into three-phase output patterns that support closed-loop servo operation. By supervising motor feedback and bus conditions, the unit maintains precise acceleration, velocity, and position in industrial automation equipment such as palletizers, machining centers, and printing presses. This operating role makes it suitable for axes that require steady torque response and repeatable motion during continuous machine cycles.

The controller operates on a stabilized DC link of 700 V, which allows the power stage to deliver consistent torque response across multiple drives that share the same supply. Its continuous phase capacity reaches 200 A, which is the maximum RMS motor current the unit can supply during sustained motion. During startup or regenerative peaks, the rectifier section can draw up to 38 A from the mains, so upstream protection must be sized for those conditions. Thermal losses reach 960 W when rated current is present, so cabinet ventilation must remove that heat to protect the switching components. Reliable operation is permitted at ambient temperatures up to 45 °C without derating, which supports installation in standard industrial control cabinets.

The controller weighs 19.5 kg, so the mounting arrangement must support the static load and normal machine vibration. The unit is in Design 3, which identifies this revision within the product line. Communication and encoder wiring use Interface Option 14, which provides the connector set and signal mapping used by this model for integration with higher-level control systems. As part of the EcoDrive line, the controller can be used in coordinated multi-axis systems with other compatible drives on the same platform.
