Code Description
B031 Software lock mode
selection
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, A320, 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.
