Check the following items before operating on the VFD.
1. Verify the load mechanical type to be driven by the VFD, and check whether overload occurred to the VFD during actual application, or whether the VFD power class needs to be enlarged? |
2. Check whether the actual running current of load motor is less than rated VFD current. |
3. Check whether the control precision required by actual load is the same with the control precision provided by the VFD. |
4. Check whether the grid voltage is consistent with rated VFD voltage. |
5. Check whether the functions required need an optional extension card to be realized. |
