Software Lock Mode
The software lock function keeps personnel from accidentally changing parameters in
the inverter memory. Use B031 to select from various protection levels.
The table below lists all combinations of B031 option codes and
the ON/OFF state of the [SFT] input. Each Check ✔ or Ex ✘
indicates whether the corresponding parameter(s) can be edited.
The Standard Parameters column below shows access is permit-
ted for some lock modes. These refer to the parameter tables
throughout this chapter, each of which includes a column titled
Run Mode Edit as shown to the right. The marks (Check ✔ or
Ex ✘) under the “Run Mode Edit” column title indicate whether access applies to each
parameter as defined in the table below. In some lock modes, you can edit only F001 and
the Multi-speed parameter group that includes A020, A220, A021–A035, and A038
(Jog). However, it does not include A019, Multi-speed operation selection. The editing
access to B031 itself is unique, and is specified in the right-most two columns below.
NOTE: Since the software lock function B031 is always accessible, this feature is not
the same as password protection used in other industrial control devices.
