Product Description:

The DKC01.3-200-7-FW/S100 is a drive controller manufactured by Bosch Rexroth Indramat within the DKC Drive Controllers series. Intended for closed-loop regulation of servo axes, it acts as the central power stage between a supply module and the motor field wiring. In automated machinery, the unit meters DC-bus energy, interprets command signals from higher-level motion cards, and modulates motor current to achieve precise position, speed, and torque targets. It is commonly used in packaging, material-handling, and assembly equipment that requires repeatable motion sequences.

The internal DC link is maintained at a nominal 700 V so the output stage can store and redistribute braking energy within the drive system. During continuous operation, the power electronics are rated to deliver 200 A of motor current, while the supply wiring must be sized for a peak draw of 38 A on the AC side. At that loading condition, the module produces 960 W of heat dissipation that must be removed by cabinet airflow. Ambient temperature is limited to 45 °C; staying below this threshold helps preserve semiconductor life and prevents thermal derating that would otherwise reduce available drive current.

The controller is Design 3, indicating a later design revision within this product line. Communication with peripheral control systems is established through Interface Option 01, which provides the factory-installed connector set used for the standardized fieldbus in the EcoDrive family. Bosch Rexroth classifies this model as an EcoDrive, a platform intended for efficient servo-axis control and regenerative energy handling during deceleration. Despite its compact footprint, the controller weighs 19.5 kg, so the cabinet mounting plate must support that static load along with vibration from machine operation.
