Check the following before applying the VFD.
l Check the load type to verify that there is no overload of the VFD during work and check whether the power class of the VFD needs to be increased. |
l Check whether the actual running current of the motor is less than the rated current of the VFD. |
l Check whether the control accuracy required by the load is the same of the VFD. |
l Check whether the grid voltage is consistent with the rated voltage of the VFD. |
l Check whether expansion card are needed for selected functions. |
