Application Scenarios

Medium and heavy-load main axes and multi-axis linkage of CNC machine tools

Textile, printing and packaging machinery requiring high synchronous precision

Automated assembly lines, large conveying equipment and gantry systems

DIAX03 system renovation and upgrade projects with SERCOS bus configuration

Automation equipment with limited cabinet space and strict requirements on communication stability

Usage and Maintenance

Ensure unobstructed air circulation inside the cabinet for effective heat dissipation.

Maintain ambient temperature below 45 °C to avoid performance degradation.

Complete all wiring of power, feedback, bus and control circuits before powering on.

Configure parameters and tune control loops via IndraWorks according to actual operating conditions.

Clean heat dissipation components and air passages, and inspect terminal connections every six months.

Calibrate control loops, feedback signals and SERCOS communication status once a year to maintain long-term stable operation.
