Configuring	Drive Parameters

The software lock function keeps personnel from accidentally changing parameters in the inverter memory. The feature has some options, but the software lock function (B21) is not protected from operator editing. You can lock all other parameters except the output frequency (F01), if desired. This allows the user to vary only the output frequency.

NOTE: Since the software lock function B31 is always accessible, this feature is not the same as password protection used in other industrial control devices.
