Have you ever considered that after the inverter is installed and parameters are set, if untrained personnel randomly modify the settings, it could lead to unnecessary issues? To prevent this problem, we can resolve it by configuring specific parameters.

Let’s refer to the instruction manual and navigate to the relevant parameter group.

 Press PRG to enter the PP parameter group, then press DATA to confirm. Use the Up key to navigate to PP-04 as shown in Figure (2). Press DATA to enter the setting, then use the Up key to set the value to 1 (parameters cannot be modified). Press DATA to save the setting as shown in Figure (3). Finally, press PRG twice to return to the main interface. The configuration is now complete.
