Input/Output Terminal Variables

This section describes the variables provided for using the following inverter terminals for the Drive
Programming function: Multi-function input terminals, multi-function output terminals, multi-function
relay outputs, analog input terminals, and analog output terminals. Use these variables as the interface
between the inverter's peripheral devices and the Drive Programming function.
Input Terminal Variables X(00) to X(07)
You can use the inverter's multi-function input terminals as the input terminal variables X(00) to X(07)
for the Drive Programming function by setting these multi-function input terminals to the general-pur-
pose input MI1 to MI8.
You can also use the input terminal variables X(00) to X(07) as word-access data, which are set to the
lower byte by using the variable Xw.

MX2:
• The status of the multi-function input terminals S1 to S7 and pulse train input RP terminal is captured
and set as bit-size variables.
This variable is read-only.
• When the Multi-function Input S1 to S7 Selection (C001 to C007) are set to 56 to 62 (MI1 to MI7:
General-purpose input), and the Pulse Train Input RP Selection (P003) is set to 02 (MI8: Gen-
eral-purpose input 8 for Drive Programming), the status of the input terminals S1 to S7 and the RP
terminal is captured and set as the input terminal variables X(00) to X(07) of the Drive Programming.
Numbers are given to the input terminal variables X(00) to X(07) according to the numerical order of
the set general-purpose inputs MI1 to MI7, not the terminal numbers S1 to S7.
RX:
• The status of the multi-function input terminals S1 to S8 is captured and set as bit-size variables. This
variable is read-only.
• When the Multi-function Input S1 to S8 Selection (C001 to C008) are set to 56 to 63 (MI1 to MI8:
General-purpose input), the status of the input terminals S1 to S8 is captured and set as the input ter-
minal variables X(00) to X(07) of the Drive Programming.
Numbers are given to the input terminal variables X(00) to X(07) according to the numerical order of
the set general-purpose inputs MI1 to MI8, not the terminal numbers S1 to S8.
