(5) Function assignment to analog input terminal 1, terminal 4, and terminal 6 (FR-A7AZ)
Functions of terminal 1, terminal 4, and terminal 6
(FR-A7AZ) of analog input can be selected and
changed by parameter.
For the terminal 1, terminal 4, and terminal 6 (FR-
A7AZ) used for analog input, frequency (speed)
