To protect the inverter parameters from being modified arbitrarily, users can set a password. The specific steps are as follows:

  • Setting a Password: In the parameter setting mode, find A1-04 (password setting), enter the desired password value, and then press the ENTER button to confirm. Next, enter the same password value in A1-05 (password) for confirmation.
  • Clearing a Password: To clear the set password, simply set the password values in both A1-04 and A1-05 to 0.

3. Parameter Initialization

When it is necessary to restore the inverter to its factory default settings, parameter initialization can be performed. The specific steps are as follows:

  • In the parameter setting mode, set A1-03 to 2220 (2-wire sequence control initialization) or 3330 (3-wire sequence control initialization), and then press the ENTER button to confirm. At this point, the inverter will be restored to its factory default settings.

4. Using the DWELL Function

The DWELL function can temporarily maintain the output frequency during motor startup or stoppage to prevent motor stall. The specific setting steps are as follows:

  • In the parameter setting mode, find b6-01 and b6-02, and set the DWELL frequency and time during startup respectively. For example, set b6-01 to 5Hz and b6-02 to 2s, so that the motor will maintain a 5Hz output for 2 seconds during startup.

5. Using the Speed Search Function

The speed search function can automatically search and set the appropriate output frequency when the motor stalls or restarts. The specific usage method is as follows:

  • In the parameter setting mode, set b3-05 to the speed search wait time (e.g., 1s). Then, trigger the speed search function through an external signal when needed, and the inverter will automatically search and set the appropriate output frequency.

2. Realizing External Potentiometer Speed Regulation

The external potentiometer speed regulation function allows users to change the output frequency of the inverter by adjusting the resistance value of an external potentiometer. The specific implementation method is as follows:

  • Wiring: Connect the output signal of the external potentiometer to terminal A1 of the inverter (multi-function analog input terminal).
  • Parameter Settings: In the parameter setting mode, set b1-01 to 1 (control circuit terminal frequency command), and set H3-01 to 0 (0~10V input). At the same time, adjust the values of H3-04 (input gain) and H3-05 (input offset) according to actual needs.

III. Fault Code Analysis
