Control modes: torque/speed/position (heavy-load optimized)

Modular design for easy maintenance and expansion

Application Scenarios

Ultra-heavy-load CNC main axes (multi-axis linkage)

Large textile/printing/packaging machinery (high sync precision)

Heavy gantry systems, large conveyors, automated lines

DIAX02 system retrofits (200 A continuous current requirement)

Cabinet-space-constrained equipment with no external cooling

Usage & Maintenance

Ensure unobstructed cabinet airflow for heat dissipation

Keep ambient temperature ≤45 °C to avoid performance loss

Complete power/feedback/bus wiring before power-on

Configure parameters via IndraWorks (match motor/load)

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

Calibrate loops/feedback annually for long-term stability
