Product Description:

The DKC01.1-040-7-FW belongs to the DKC Drive Controllers series manufactured by Bosch Rexroth Indramat. Classified as an EcoDrive unit, it functions as a power and control interface between the plant's DC bus and individual servo or induction motors. Within automated production cells, the controller interprets velocity and position commands, modulates transistor switching, and delivers phase-accurate current so that actuators achieve precise motion profiles required for pick-and-place, conveying, or forming operations.

The drive's continuous output rating reaches 40 A, which is the maximum motor current it can supply without derating. Its internal link circuit is referenced to a nominal DC-bus potential of 700 V, and this voltage is provided by a front-end supply module that serves as the energy reservoir for rapid acceleration. A storage network of 0.15 mF smooths this bus, limiting ripple and protecting downstream components. When regenerated energy causes the link voltage to climb, a braking resistor is activated once the level hits 820 V, preventing overvoltage faults. All live parts remain behind a housing rated at IP20, so the unit is suitable for cabinet-mounted equipment while still allowing convection airflow across the heat sink. Control electronics draw 0.7 A from a 24 V logic supply, and the BB contacts on the terminal strip switch at 1 A to feed external interlocks.

Physical integration is simplified by overall dimensions of 360 × 210 × 65 mm, permitting high packing density on DIN rails. The drive requires a cooling clearance of 80 mm above and below the unit so natural air circulation can remove switching losses. The controller tolerates ambient moisture up to 25 g/m³ and will continue operating at temperatures as high as +55 °C with reduced nominal output, supporting installation in non-conditioned enclosures. The unit weighs 4.4 kg. The design remains stable up to 1000 m altitude with relative humidity not exceeding 95%.
