Core Functions

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

Compact W‑type internal cooling for space‑saving cabinet installation

Integrated DSF digital feedback for accurate motor positioning

Modular design for flexible communication/feedback upgrades

Comprehensive protection: over/undervoltage, overcurrent, short circuit, overheat, feedback loss

Torque/speed/position control modes

Application Scenarios

Medium‑precision CNC machine axes (milling/turning)

Textile, printing, and packaging machinery (single/dual‑axis)

Assembly lines and material handling systems

Space‑constrained control cabinets (no external blower required)

DIAX02 system upgrades with 50 A continuous current

Usage and Maintenance

Ensure cabinet airflow ≥ 350 m³/h for internal cooling

Keep ambient ≤45 °C to avoid derating

Complete power/feedback/control wiring before power‑on

Configure via IndraWorks (match motor/load parameters)

Clean heatsink/air passages every 6 months; inspect terminals

Calibrate control loops/feedback annually
