Parameter Write Protection
This section describes the functions you can use to protect Inverter parameter settings from rewriting.

Soft Lock Function

• Use the soft lock function to set whether to enable or disable the writing of parameter data. This helps
prevent data rewriting due to erroneous operation.
• In the Soft Lock Selection (b031), select to which parameter data you want to apply the soft lock.
• To control the soft lock function via a multi-function input terminal, set the Multi-function Input S1 to
S8 Selection to 15 (SFT: Soft lock).
• Setting the Soft Lock Selection (b031) to 10 (Data can be changed during RUN) enables to change
parameter data, which is marked with under "Changes during operation" in Section 4 Parameter List,
during operation.
Note that only this setting is provided for disabling, instead of enabling, the parameter lock function.
