Usage and Maintenance

Guarantee sufficient air circulation inside the cabinet to ensure heat dissipation.

Keep ambient temperature below 45 °C to prevent performance decline.

Complete wiring of power circuit, feedback circuit and control circuit before power-on commissioning.

Set operating parameters through IndraWorks according to actual motor and load conditions.

Clean internal air passages and heat dissipation components every six months and inspect terminal connections regularly.

Calibrate control loops and feedback signals once a year to maintain long-term stable operation.
