Supports torque, speed and position three standard control modes.

Modular structure facilitates on-site maintenance and function expansion.

Application Scenarios

High-power main axes of heavy-duty CNC machine tools

Large textile, printing and packaging machinery with heavy load

Heavy-duty handling robots and automated production lines

DIAX02 system renovation and replacement projects requiring 150 A continuous current

Automation equipment with limited cabinet space and no external cooling conditions

Usage and Maintenance

Maintain sufficient air circulation inside the cabinet to guarantee heat dissipation.

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

Finish all power, feedback and control wiring before power-on commissioning.

Set parameters through IndraWorks according to actual motor and load conditions.

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

Calibrate control loops and feedback signals once a year to keep long-term stable operation.
