1. If the fault code on the Yaskawa servo drive is UV1, it means that the low voltage of the main circuit is lower than the low voltage standard of 200V, at this time, we need to check whether there is a problem with the wiring of the power supply;

2. If the fault code on the Yaskawa servo drive is UV2, it means that the low voltage of the control loop is lower than the low voltage standard, and we need to check whether the capacity of the power supply is normal;

3. If the fault code on the Yaskawa servo drive is UV3, it means that the electromagnetic contactor inside the inverter may be faulty

4. If the fault code on the Yaskawa servo drive is UV, then there may be an instantaneous power outage, the main reasons are as follows, the first is that the voltage of the main circuit is lower than the voltage standard, and the second may be that the contactor is faulty;

5. If the fault code on the Yaskawa servo drive is OC, then the output current of the inverter may exceed the output current standard, and we need to check whether the impedance insulation of the inverter is working normally;

6. If the fault code on the Yaskawa servo drive is GF, then it means that the inverter has a grounding fault, at this time, I need to check whether the inverter has a fault of insulation deterioration, and at the same time, we also need to check whether the wiring of the inverter is damaged;

7. If the fault code on the Yaskawa servo drive is OV, then it means that the DC voltage of the main circuit is higher than the overvoltage standard of 200V:

8. If the fault code on the Yaskawa servo drive is SC, then it means that the inverter has a load short circuit, we need to check whether there is a short circuit on one side of the inverter output, and then check whether the insulation and impedance of the inverter are normal;

9. If the fault code on the Yaskawa servo drive is PUF, then it means that the fuse inside the inverter is broken, it may be that the fuse of the main circuit is blown out, or the fuse of the DC circuit is blown out, and then we need to check whether the work of the crystal module is normal, and then check that the load is not short-circuited.
