Drive Programming User’s Manual (I580-E2)
9-4 Drive Programming User Variables
You can use the inverter's multi-function input terminals as the input terminal variables X(00) to X(11)
for the Drive Programming function by setting these multi-function input terminals to the general-pur-
pose input MI1 to MI12.
You can also use the input terminal variables X(00) to X(11) as word-access data, which are set to the
lower byte by using the variable Xw.
• The status of the multi-function input terminals S1 to S7 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 49 to 60 (MI1 to MI11:
General-purpose input), the status of the input terminals S1 to S7 is captured and set as the input ter-
minal variables X(00) to X(11) of the Drive Programming.
Numbers are given to the input terminal variables X(00) to X(11) according to the numerical order of
the set general-purpose inputs MI1 to MI11, not the terminal numbers S1 to S7.
• The input terminal variable (word access) Xw is a function to use the input terminal variables X(00) to
X(11) as a word-size variable. This variable is read-only.
• The input terminal variables X(00) to X(11) are set to the lower byte. For the upper byte and unused
input terminal variables, zero is read out.
