Product Description:
The DKC1.1-030-3 is a drive controller produced by Bosch Rexroth Indramat within the DKC Drive Controllers series. The EcoDrive interfaces between plant power and a servo motor, regulating current and voltage according to commands from the motion control system. It supports position-controlled and speed-controlled axes in industrial automation equipment such as pick-and-place gantries, packaging machines, and light machining centers.
The controller connects to plant power through a single-phase input rated at 1.8 kVA and supplied with 1 × AC 230 V when operating with moderate loads. For higher dynamic demands, the three-phase input provides a capacity of 3.2 kVA from a 3 × AC 230 V supply. The control board draws 0.7 A, keeping the load on the auxiliary supply low. The DC link contains 0.15 mF of capacitance to smooth the rectified voltage, while a line tolerance of ±10% allows operation during moderate fluctuations in the incoming power. An internal blower moves cooling air across the power semiconductors to remove heat from the controller. The IP20 enclosure provides protection against contact with hazardous internal components and is intended for installation inside a closed control cabinet. During axis deceleration, the integrated resistor bank can absorb up to 5.0 kWs of regenerated energy to protect the DC bus from excessive voltage. Forced airflow and suitable cabinet clearances must be maintained around the module during operation.
A dedicated bleeder resistor can continuously dissipate 0.15 kW of regenerated power, so an external braking module is not required when the application remains within this limit. The intermediate circuit stores 15 Ws of energy to help bridge brief interruptions in the incoming power. The controller can operate at ambient temperatures up to 55 °C when the required derating measures are applied. Installation is permitted at altitudes up to 1,000 m and in environments with relative humidity up to 95%. The assembly weighs 4.4 kg, allowing it to be secured to a standard control panel without additional structural bracing.
