Core Functions

Three‑loop control (current/speed/position) for high precision

Digital servo feedback for accurate positioning

Convection cooling for cabinet installation (no external fan)

Full protection: overvoltage/undervoltage/overcurrent/short‑circuit/overtemperature/feedback loss

Torque/speed/position control modes

Modular design for easy maintenance and expansion

Application Scenarios

Medium/heavy‑load CNC main axes

Large textile, printing, packaging machinery

Gantry systems, heavy conveying lines

DIAX02 system retrofits (100 A continuous)

Cabinet‑space‑constrained equipment without external cooling

Usage & Maintenance

Ensure cabinet airflow for heat dissipation

Keep ambient ≤45 °C to avoid derating

Complete power/feedback/bus wiring before power‑on

Set parameters via IndraWorks (match motor/load)

Clean heat paths every 6 months; check terminals

Calibrate loops/feedback annually
