Usage and Maintenance

Ensure ≥50 mm clearance around unit for unobstructed cabinet airflow

Keep ambient ≤45 °C; monitor heat sink temperature

Complete power/feedback/bus wiring before power‑on; torque terminals to spec

Configure via IndraWorks: Match motor parameters, tune loops, set up fieldbus

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

Calibrate loops, feedback, and communication annually for long‑term stability
