3. Check whether there is any short circuit, open circuit or damage to the motor cable insulation in the motor cable;
4. Check whether the AC input power voltage is within the power supply voltage working range allowed by the inverter product technical specifications, or whether the grid voltage is stable;
5. Check on-site wiring, signal wires and power wires should be wired separately;
6. Confirm whether the motor wire is connected to the U, V, W terminals of the inverter;
7. Check whether the acceleration and deceleration time is too short;
8. Check whether the V/F curve and manual torque boost value are appropriate;
9. Check whether the power of the inverter matches the power of the motor to be driven;
