Product Description:
The DKC22.3-040-7-FW is a drive controller produced by Bosch Rexroth Indramat within the DKC Drive Controllers series. Classified by the manufacturer as an EcoDrive unit, it regulates servo axes and induction motors in industrial automation cells and other automated lines, supplying precision speed and torque commands through its embedded power stage and control electronics.
This controller operates with a DC-bus that sits at 700 V, so the internal inverter can modulate high-energy pulses without saturation. It can deliver a continuous phase current of 40 A, matching medium-frame motors used on packaging lines or pick-and-place gantries. Output frequency extends to 800 Hz, letting the connected motor reach commanded speeds far above mains frequency. Surplus regenerative energy is routed to an integrated bleeder that dissipates 0.15 kW continuously, while the electronics themselves release 180 W of heat during rated operation. The housing carries the hardware series code 22, guaranteeing compatibility with companion firmware and accessories from the same generation.
Short bursts of braking energy are handled by the bleeder resistor at 10 kW, preventing DC-bus over-voltage during rapid deceleration. The enclosure meets IP20 requirements, so it must be installed inside a control cabinet that provides the necessary dust and touch protection. Communication expansion is handled through Interface Option 22, which accepts matching fieldbus cards specified for this platform. Mechanical and electrical details follow Design code 3; the current production release is 3, ensuring spare units remain form-fit with earlier DKC22 hardware. Together, these parameters define thermal margins, enclosure demands, and network connectivity for predictable controller behavior under cyclic industrial loads.
