Product Description:
The DKC14.3-040-7-FW is a drive controller produced by Bosch Rexroth Indramat within the DKC Drive Controllers series. As an axis module, it processes command signals from a motion control system and converts DC-bus energy into regulated three-phase output for synchronous or induction motors. By closing the speed and position loops in real time, the unit supports coordinated multi-axis motion in packaging machines, material-handling cells, and other automated equipment where repeatable acceleration, deceleration, and positioning are required. This arrangement lets a central control system send motion commands while the drive handles the fast electrical corrections needed to keep motor response stable under changing load conditions.
The controller operates on a DC link stabilized at 700 V, which gives the power section enough headroom for rapid acceleration and regenerative braking. Interface option code 14 includes the SERCOS optical bus, allowing deterministic communication with higher-level PLCs and synchronized data exchange between motion axes. During normal duty, the power stage delivers a continuous output of 40 A, while the upstream supply must allow a peak line draw of 16 A on the three-phase input. Thermal losses reach 180 W at rated current, so cabinet airflow or other heat removal must prevent heat buildup around the power semiconductors and control electronics.
Mechanical construction uses design code 3, marking the third housing revision and maintaining compatibility with established mounting patterns used in earlier modules. Safe operation is permitted up to an ambient temperature of 45 °C, after which derating or added cooling is needed to protect the power section and control electronics. The enclosure weighs 5.7 kg, which keeps panel loading moderate and simplifies mounting in compact cabinets. The controller is part of the EcoDrive platform, so it uses a common parameter structure and shared diagnostic behavior across that range.
