Check the machine before beginning to use the VFD:
1. Check the load type to verify that there is no overload of the VFD during work and check that whether the drive needs to modify the power degree. |
2. Check that the actual current of the motor is less than the rated current of the VFD. |
3. Check that the control accuracy of the load is the same of the VFD. |
4. Check that the incoming supply voltage is correspondent to the rated voltage of the VFD. |
5. Check that the communication needs option card or not. |
