Soft Lock Function
Use this function to prohibit writing of each parameter. This helps prevent data rewrite due to
erroneous operation.
For the soft lock selection through the signal input from the terminal (b031 = 00 or 01), refer to the
Soft Lock Function of the Multi-function Input section in "Reset" (page 4-50).
Allocate 15 (SFT) to the desired multi-function input.
