6.2 Switching of Operation

6.2.1 Easy sequence function selection (A017)

To enable the easy sequence function, specify "01" (enabling) for the easy sequence function selection
(A017). When the easy sequence function is enabled, the FW terminal is switched to the PRG terminal,
which is used to run the sequence program downloaded to the inverter. (The FW terminal does not
function as the terminal to input the forward-rotation command while the easy sequence function is
operating.)
Function code
A017

6.3 Switching of Input/Output Terminals

6.3.1 Program run signal input terminal (PRG terminal)

Turning on the PRG (FW) terminal runs the sequence program downloaded to the inverter. When the
PRG terminal is off, the inverter does not accept the operation command input via the RV terminal, but
waits until the sequence program runs. If the PRG terminal is turned off while the sequence program is
running, the program stops, and all operation command input terminals are turned off.

6.3.2 General-purpose contact input terminals

You can assign functions "56" (MI1) to "63" (MI8) to terminals 1 to 8 (C001 to C008) to use these
terminals as general-purpose input terminals for the easy sequence function. The table below lists the
inverter terminal functions and program variables corresponding to the terminal functions.
When a general-purpose input function is assigned to an intelligent input terminal, the status of the
terminal is reflected in the corresponding program variables (X (00) to X (07) or Xw). If the easy sequence
function is disabled or a program that does not use variables "X (00)" to "X (07)" and "Xw" runs, intelligent
input terminals 1 to 8 will be ineffective even when functions MI1 to MI8 are assigned to the terminals.
You can also assign functions other than MI1 to MI8 to the intelligent input terminals and operate the
terminals for those functions even while a sequence program is running. If both the easy sequence input
and intelligent input functions have been assigned to an intelligent input terminal, the terminal functions
when either input is effective (i.e., both inputs are ORed).
