Product Short Description
Product Name:
EcoDrive03 DKC03.3 Digital Intelligent AC Servo Drive Controller
Product Overview:
The DKC03.3-040-7-FW is a 40 A intelligent servo amplifier with PROFIBUS-DP communication and integrated motion functions. It executes positioning blocks, electronic gearing and cam tasks for decentralized automation systems and connects directly to PLC or HMI networks.
Description
Technical Specifications:

Control supply 24 V DC. DC bus capacitance 0.27 mF. Power dissipation 180 W. Internal blower cooling. Protection class IP20. Operating temperature 0 to 45 C rated, up to 55 C derated. Storage temperature -30 to 85 C. Relative humidity 95 percent non-condensing. Dimensions 360 mm height, 65 mm width, 261 mm depth. Weight 5.7 kg. Short-circuit current rating 42,000 A rms.
Functional Features:
PROFIBUS-DP communication, up to 64 stored positioning blocks, integrated position control, RS232 or RS485 diagnostic interface, compatibility with MKD and MHD digital AC motors, software travel limits, electronic cam and gearing functions.
Structure And Materials:
Sheet-metal booksize enclosure, control PCB, IGBT output stage, DC bus capacitors, blower, PROFIBUS connector, diagnostic serial port, motor and feedback terminals, firmware module slot.
Working Principle:
The supply rectifier charges the 700 V DC bus. The PROFIBUS master sends setpoints and motion commands. The drive converts commands into PWM output through current, speed and position loops, uses motor encoder or resolver feedback, and returns diagnostic data to the controller.
Installation Requirements:
Install vertically in a control cabinet. Maintain 150 mm top clearance and 80 mm bottom clearance for blower airflow. Connect main power, 24 V control, PROFIBUS cable with correct bus termination and address, motor power and feedback cables. Ground the metal enclosure.
Application Scenarios:
Assembly equipment, packaging lines, printing machines, handling systems, CNC axes, conveyor systems and robotics.
Usage Precautions:
Install firmware matching the ordered drive function. Terminate PROFIBUS at both ends of the segment. Do not block the blower inlet or outlet. Verify motor parameters before first run. Keep humidity below 95 percent and avoid condensation.
