2. Input pins/Output pins
Input pin
Name Function
Data
type
Setting value Time when a value is valid
Execute
A main program is
backed up when
there is a transition
in the Execute
input pin’s signal
from low to high.
BOOL True/False -
FileName Filename WORD K0~K4095
The value of the FileName
input pin is valid when there
is a transition in the Execute
input pin’s signal from low to
high.
State output pin
Name Function
Data
type
Time when there is
a transition in an
output pin’s signal
from low to high
Time when there is a
transition in an output pin’s
signal from high to low
Done
The execution of
the motion control
function block is
complete.
BOOL

There is a
transition in the
Done output
pin’s signal
from low to
high when the
writing of
values is
complete.

There is a transition in
the Done output pin’s
signal from high to low
when there is a
transition in the
Execute input pin’s
signal from high to low.
Busy
The motion control
function block is
being executed.
BOOL

There is a
transition in the
Busy output
pin’s signal
from low to
high when
there is a
transition in the
Execute input
pin’s signal
from low to
high.

There is a transition in
the Busy output pin’s
signal from high to low
when there is a
transition in the Error
output pin’s signal from
low to high.

There is a transition in
the Busy output pin’s
signal from high to low
when there is a
transition in the Done
output pin’s signal from
low to high.
Error
An error occurs in
the motion control
function block.
BOOL

Input values
are incorrect.

There is transition in
the Error output pin’s
signal from high to low
when there is a
transition in the
Execute input pin’s
signal from high to low.
3. Troubleshooting
Error Troubleshooting
The values of input pins in the motion
control function block are incorrect. Check whether the values of the input pins
are in the ranges allowed.
