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
9 or Ex U indicates
whether the corresponding parameter(s) can be edited. The
Standard Parameters column below shows access in permitted 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
9 or Ex U) 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.
