Supports torque, speed and position control modes to meet diverse heavy-load working requirements.

Modular design facilitates daily maintenance and later function expansion.

Application Scenarios

Heavy-load main axes of CNC machine tools with multi-axis linkage

Large textile, printing and packaging machinery requiring high synchronous precision

Heavy-duty gantry systems, conveying equipment and automated production lines

DIAX02 system renovation projects adopting DS04 SERCOS bus

Automation equipment with limited cabinet space and strict requirements for communication reliability

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.
