Usage and Maintenance

Ensure unobstructed cabinet airflow for cooling

Keep ambient ≤45 °C to avoid performance loss

Complete power/feedback/control wiring before power-on

Parameterize via IndraWorks per motor/load

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

Calibrate loops/feedback annually
