Software Lock

When the terminal [SFT] is turned ON, the data of all the parameters and functions
(except the output frequency, depending on the setting of B031) 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 B031 to select whether the output frequency is excluded from the lock
state or is locked as well.
