Core Functions

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

High‑power 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

Heavy‑duty CNC machine main spindles and axes

Large textile, printing, and packaging machinery with extreme loads

High‑power material handling and gantry systems

DIAX02 system upgrades requiring 200 A continuous current

Automation equipment with limited cabinet space and no external cooling

Usage and Maintenance

Ensure cabinet airflow ≥ 500 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
