Modular design for easy maintenance and expansion

Application Scenarios

Heavy‑load main axes of CNC machine tools (digital encoder motors)

Large textile, printing, packaging machinery

Heavy‑duty gantries, conveying lines, automated production lines

DIAX02 system retrofits requiring 150 A + digital feedback

Cabinet‑space‑limited equipment without external cooling

Usage & Maintenance

Ensure unobstructed cabinet airflow for cooling

Keep ambient ≤45 °C to avoid derating

Complete power/feedback/control wiring before power‑on

Set parameters via IndraWorks (motor/load‑specific)

Clean heat sinks/air passages every 6 months; inspect terminals

Calibrate loops/encoder signals annually
