Core Functions

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

External cooling for 150 A continuous heavy‑duty operation

Factory‑integrated digital servo feedback (D‑type) for plug‑and‑play with DSF motors

Modular card‑based expansion for SERCOS/analog interfaces

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

Torque/speed/position control modes

DIAX02 firmware compatible (FW module ordered separately)

Application Scenarios

High‑power CNC main/spindle axes (heavy cutting)

Heavy‑duty textile, printing, packaging machinery

Large multi‑axis handling robots and assembly lines

High‑torque motion requiring 150 A continuous current

DIAX02 system upgrades (digital feedback axes)

Usage and Maintenance

Ensure cabinet airflow ≥ 450 m³/h for external 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
