Software Lock Mode
The software lock function keeps personnel from accidentally changing parameters in
the inverter memory. Use


The table below lists all combinations of

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 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

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

and the Multi-speed parameter group that includes








NOTE: Since the software lock function

is always accessible, this feature is not the
same as password protection used in other industrial control devices. So if you want to
use password function, use parameter

together with the

. See section 4-104 for
detailed explanation of the password function.
