Using Intelligent Input Terminals

When the terminal [SFT] is turned on, the data of all the parameters and functions except the output frequency is locked (prohibited from editing). When the data is locked, the keypad keys cannot edit inverter parameters. To edit parameters again, turn off the [SFT] terminal input.

Use parameter B31 to select whether the output frequency is excluded from the lock state or is locked as well.
