Usage and Maintenance

Maintain smooth air circulation inside the cabinet to guarantee heat dissipation effect.

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

Complete wiring of power, resolver feedback and control circuits before power-on.

Set parameters via IndraWorks according to actual motor and load conditions.

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

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