2. Input pins/Output pins
Input pin
Name Function
Data
type
Setting value Time when a value is valid
Axis
Motion axis
number
WORD K1~K16
The value of the Axis input
pin is valid when there is a
transition in the Execute
input pin’s signal from low to
high.
Execute
Motion is
started when
there is a
transition in
the Execute
input pin’s
signal from low
to high.
BOOL True/False -
Position
Present
position of the
axis specified
DWORD
K-2,147,483,648~
K2,147,483,647
The value of the Position
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

The writing of a
position 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 Done 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 Error 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.
