Application Scenarios

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

Large textile, printing and packaging machinery requiring synchronous operation

Gantry systems and heavy-duty automated production and conveying lines

DIAX02 system renovation projects adopting DS03 SERCOS bus

Automation equipment with limited cabinet space and high requirements for communication stability

Usage and Maintenance

Maintain sufficient unobstructed air circulation inside the cabinet for heat dissipation.

Keep ambient temperature below 45 °C to avoid performance decline.

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

Set parameters and configure bus network via IndraWorks according to actual operating conditions.

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

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