This chapter explains the settings of the applied functions.
The parameter number structure is indicated below.
This chapter explains how to set the first setting. For the second setting, follow the
same procedure. The setting value and operation are common.
The function assigned to In/Output terminals is indicated as a combination of three dig-
its numbers and alphabets, like “023[F-OP].” For more details of the functions, refer to
the <List of input terminal functions> on page C-44 and the <List of output terminal
functions> on page C-49.
