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 lists Low and
High level access 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 two marks (Check
✔ or Ex ✘) under the “Lo Hi” subtitle indicate whether
Low-level and/or High-level 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.
