Multifunction Input/Output Functions
List
This section describes the input/output signals of the inverter.
7-2-1
Multifunction Input Selection
By allocating the following functions to the Input Terminal [DI1] Function Selection to Input Terminal
[DI7] Function Selection (E01 to E05, E98, E99), the set function can be operated. However, “98: FW
(Forward Run/Stop)” and “99: RV (Reverse Run/Stop)” can be allocated to only Input Terminal [DI6]
Function Selection (E98) or Input Terminal [DI7] Function Selection (E99).
By setting data in which 1000 is added to the set data of the following functions that are to be used, it
is possible to switch the input terminals [DI1] to [DI7] from an NO contact input to an NC contact input.
However, as a standard, “6: STP (3-wire stop),” “9: EXT (External trip),” “23: ATR (Torque command
input permission)” and “30: STOP (Force to stop (30 = Active OFF; 1030 = Active ON))” are set to an
NC contact, and change to an NO contact by setting data in which 1000 is added.
If the same function is allocated to the multifunction input terminals, and if any one of the multifunction
input terminals to which the function is allocated, except for the exceptions below, turns ON, the func-
tion is handled as ON.
Exception: If all terminals to which “9: EXT (External trip),” “30: STOP (Force to stop),” “38: ROK (Per-
mission of Run command),” “98: FW (Forward Run/Stop)” or “99: RV (Reverse Run/Stop)” is allocated
are ON, the function is handled as ON.
Input terminals or output terminals can be forcibly manipulated via communication by setting Support
Tool Link Function Selection (y99). (Refer to 8-10 Command via Communications on page 8-87.)
When operation via communication is set to enabled (y99 = 2, 3), the function allocated to the input
terminal can be operated via communication. Handling of commands via communication and com-
mands via terminal blocks differs according to each individual function that is allocated.
For how to handle commands when operation via communication is enabled (y99 = 2, 3), refer to the
symbols in the “Communication function” column in the table below. The following shows the mean-
ings of the symbols.
E: Signals wired to the input terminal are disabled and operation follows commands instructed by Op-
eration command (S06).
O: O: Handled as ON when whichever of signals wired to the input terminal or commands instructed
by Operation command (S06) are ON.
A: A: Handled as ON when both signals wired to the input terminal and commands instructed by Op-
eration command (S06) are ON.
-: Changes cannot be made by the communications function
