7-6 Digital Operator and Operation Functions
This section describes the Digital Operator and other operation functions.
Use this function to protect various parameter settings against changes. This helps prevent data rewrit-
ing due to erroneous operation.
Use the table below to select which type of soft lock you want to apply.
To use this function from a multi-function input terminal, allocate the Multi-function Input S1 to S7 Selec-
tion (C001 to C007) to 15 (SFT).
Setting b031 to 10 (Data can be changed during RUN) enables you to change the parameters marked
with Enabled under “Changes during operation” in
Section 4 Parameter List during operation.
Alternatively, you can use the password function to protect parameter data. Refer to 7-6-9 Password
Function on page 7-57.
Precautions for Correct Use
When the Soft Lock Selection (b031) is set to prohibit changes of the initialization-related
parameters (b084, b094, b180), the initialization cannot be executed. Change the Soft Lock
Selection (b031) to enable the initialization.
For details on the parameter initialization, refer to 5-1-2 Parameter Initialization on page 5-6.
