Core Functions

Three-loop control (current/speed/position) for high-precision motion performance

Digital servo feedback ensures accurate positioning and speed regulation

Modular design supports flexible function expansion via plug-in modules

Cabinet convection cooling adapts to narrow installation spaces

Comprehensive protection: Overvoltage/undervoltage/overcurrent/short circuit/overheating/feedback loss

Supports torque/speed/position control modes for diverse load requirements

Application Scenarios

Medium-to-heavy duty main axes of CNC machine tools

Large textile, printing, and packaging machinery

Gantry systems, heavy-duty conveying lines, and automated production lines

DIAX02 system retrofits requiring 100 A continuous current

Automation equipment with limited cabinet space and no external cooling

Usage and Maintenance

Ensure unobstructed cabinet airflow for effective heat dissipation

Maintain ambient temperature ≤45 °C to avoid performance derating

Complete power/feedback/bus wiring before power-on

Configure parameters and expansion modules via IndraWorks based on motor/load conditions

Clean heat dissipation components every 6 months; inspect terminal connections regularly

Calibrate control loops and feedback signals annually for long-term stability
