To use this function from a multi-function input terminal, allocate the Multi-function Input 1 to 7 Selec- tion
(C001 to C007) to 15 (SFT).

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 5-5.
