Core Functions

High-speed three-loop control delivers fast dynamic response and steady operation under heavy loads.

Dual feedback support adapts to different motor types and various industrial environments.

Internal convection cooling suits standard cabinet installation without extra cooling equipment.

Complete protection against overvoltage, undervoltage, overcurrent, short circuit, overheating and feedback signal loss.

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

Modular design simplifies daily maintenance and functional expansion.

Application Scenarios

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

Large textile, printing and packaging machinery

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

DIAX03 system renovation and upgrade projects

Automation equipment with limited cabinet space and convection cooling design

Usage and Maintenance

Maintain unobstructed air circulation inside the cabinet to ensure effective heat dissipation.

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

Finish all wiring of power, feedback, bus and control circuits before powering on the device.

Set 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 and feedback signals once a year to sustain long-term reliable operation.
