Usage and Maintenance

Install the drive vertically and ensure unobstructed external cooling air duct.

Keep ambient temperature below 45 °C and altitude within 1000 meters during operation.

Complete wiring of DC bus, control power, motor feedback and fieldbus before commissioning, and configure parameters via IndraWorks software.

Clean dust and inspect terminal connections every 6 months. Calibrate control loops once per year for stable operation.
