Chapter 7 Explanation of Functions
7 - 12
7.3 Setting the intelligent I/O terminal function
7.3.1 Intelligent input terminal setting
You can assign the functions described below to intelligent in put terminals [1] to [5]. To assign the desired
functions to the terminals, specify the desired data listed in the table below for terminal settings "C001" to
"C005". For example, "C001" corresponds to intelligent input terminal [1].
You can select the a-contact or b-contact input for individual intelligent input terminals.
You can assign one function only to an intelligent input terminal. If you have attempted to assign a function
to two or more intelligent input terminals, the function is assigned to only the terminal to which you have
last attempted assignment. Function data "NO" (no assign) is assigned to other terminals, and those
terminals are ineffective in terms of functions.
After assigning the desired functions to intelligent input terminals [1] to [5], confirm that the assigned
functions have been stored on the inverter.

7.3.2 Input terminal a/b (NO/NC) selection
The input terminal a/b (NO/NC) selection function allows you to specify a-contact or b-contact input for
each of the intelligent input terminals [1] to [5].
An a-contact turns on the input signal when closed and turns it off when opened.
An b-contact turns on the input signal when opened and turns it off when closed.
The terminal to which the reset (RS) function is assigned functions only as an a-contact.
