Product Description:
The DKC11.1-040-7-FW is a Bosch Rexroth Indramat drive controller from the DKC Drive Controllers series. Classified by the manufacturer as an EcoDrive unit, it governs three-phase servo axes by translating command signals into regulated motor currents while managing regenerated energy through its integrated bleeder circuit. This hardware is identified as design version 1 and is supplied with interface option 11 for system-level communication.
The controller delivers a continuous motor phase current of 16 A at a 4 kHz switching frequency and can supply a rated and peak output of 40 A for short load surges. Its DC-bus section is charged to 700 V and stabilized by 0.15 mF of capacitance, storing 15 Ws for immediate dynamic response. Regenerated power is dissipated through the bleeder, which can handle 0.15 kW continuously and up to 10 kW (0.5 s) during rapid deceleration; the bleeder also accepts a maximum feedback energy of 5.0 kWs. Internal blower cooling maintains component temperatures while the unit releases 180 W of heat under nominal conditions without the bleeder engaged. Additional electrical figures include a 0.7 A control supply requirement and a three-phase operating mode that matches standard industrial mains.
An IP20 housing protects the electronics against solid objects and allows cabinet mounting in humid production areas up to 95% relative humidity and 25 g/m³ absolute moisture. Full performance is available to ambient temperatures of 55 °C and installation elevations reaching 1000 m above sea level without derating. The controller weighs 4.4 kg, easing placement on DIN rails or backplates. Storage and handling are simplified by its 0.15 kW continuous bleeder output, 180 W dissipation baseline, and internally driven airflow, providing stable operation when cabinet space and environmental limits are tight.
