Supports torque, speed and position control modes to meet heavy-load operation demands.

Modular structure facilitates daily maintenance and function expansion.

Application Scenarios

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

Large textile, printing and packaging machinery operating in harsh industrial environments

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

DIAX02 system renovation projects requiring resolver feedback

Automation equipment with limited cabinet space and high mechanical vibration resistance requirements

Usage and Maintenance

Maintain smooth air circulation inside the cabinet to guarantee effective heat dissipation.

Keep ambient temperature below 45 °C to prevent performance degradation.

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

Set parameters via IndraWorks according to actual motor and operating conditions.

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

Calibrate control loops and resolver signals once a year to maintain long-term stable operation.
