I/O Control Commands

Use these I/O control commands to control inputs and outputs. Although you can control I/Os with the 
(Assignment) command, the I/O control commands can efficiently use the program capacity because
their arguments require smaller data size.
var  X(i)
Command
Assigns one bit of the status of the input termi-
nal variable to <variable>.
Note The input terminal variable is a variable that detects the status of the inverter's input terminal.
MX2: Set the Multi-function Input S1 to S7 Selection (C001 to C007) to 56 to 62 (MI1 to MI7: General-purpose input).
Set the Pulse Train Input RP Selection (P003) to 02 (MI8: General-purpose input 8 for Drive Programming).
RX: Set the Multi-function Input S1 to S8 Selection (C001 to C008) to 56 to 63 (MI1 to MI8: Gen-
eral-purpose input).
<Assignment example>
X(00)  MI1 (function No. 56)
X(01)  MI2 (function No. 57)
X(02)  MI3 (function No. 58)
X(03)  MI4 (function No. 59)
X(04)  MI5 (function No. 60)
X(05)  MI6 (function No. 61)
X(06)  MI7 (function No. 62)
X(07)  MI8 (MX2: P003 02/RX: function No. 63)
Note For details, refer to 5-2 Input/Output Terminal Variables on page 5-5.
 Example
In the above example, the status of the input terminal X(01) is monitored with the parameter UMon(0) (d025).
Block number
1 Assigns X(01) to UMon(0).
2 Jumps to the block 1: loop_ unconditionally.


<variable> : X(i)

The following settings are required. The numerical order of input terminal variables follows the
numerical order of the set general-input numbers.
Flowchart
variable: any variable (the variable value is 0 or 1)
i: input terminal variable (range 00 to 07)
