SJ300 Inverter

Intelligent Input

Terminal

Overview

Each of the eight intelligent terminals may be assigned any of the options in the following table. When you program one of the option codes for terminal assignments C001 to C008, the respective terminal assumes the function role of that option code. The terminal functions have a symbol or abbreviation, which we use to label a terminal using that function. For example the “Reverse Run” command is [RV]. The physical label on the terminal block connector is simply 1, 2, 3, 4, 5, 6, 7, or 8. However, schematic examples in this manual also use the terminal function symbol (such as [RV]) to show the assigned option. The option codes for C011 to C019 determine the active state of the logical input (active high or active low).

Summary Table - This table shows all forty-four intelligent input functions at a glance. Detailed descriptions of these functions, related parameters and settings, and example wiring diagrams are in “Using Intelligent Input Terminals” on page 4–11.
