Application Scenarios

Main axes and spindle drives of large CNC machine tools

Heavy-duty packaging, printing and textile machinery

High-load material handling equipment and gantry systems

Industrial automation equipment under 380–480 V AC power supply

On-site replacement and system upgrade of legacy DKC01.3 series servo systems

Usage and Maintenance

Install the drive vertically and reserve enough space for ventilation and heat dissipation

Complete all power, motor and signal wiring before powering on

Use shielded cables for encoder and signal lines, and separate them from power cables

Clean cooling fans and dust filters every 3 to 6 months in dusty environments

Check terminal tightness and indicator status regularly

Load FWA firmware and complete parameter commissioning via IndraWorks or DriveTop software
