Output on
Position
(
OUTFNCi-H
)
The Output on Position function for axis 1 (
OUTFNC25-H
) can be assigned only to output
#25 (
OUT-A
), and the Output on Position function for axis 2 (
OUTFNC26-H
) can be assigned
only to output #26 (
OUT-B
). The Output on Position parameters are configured with the
OUTPA
and
OUTPB
commands:
1
st
data field (
b
) :
1
enables the output on position function;
Ø
disables the function.
2
nd
data field (
b
):
1
sets the position comparison in the 3
rd
data field (
r
) to an incremental
position;
Ø
sets the position comparison in the 3
rd
data field (
r
) to an absolute position.
3
rd
data field (
r
): Represents the scalable distance with which the actual (encoder) position is to
be compared (distance is either incremental or absolute, depending on the
setting of the 2
nd
data field).
4
th
data field (
i
): Represents the time (in milliseconds) the output is to stay active. If this data
field is set to
Ø
, the output will stay active for as long as the actual distance
equals or exceeds the distance specified in the 3
rd
data field. (This is valid only
for the absolute mode—2
nd
data field set to
Ø
)
When an incremental distance is used for comparison (2
nd
data field set to
1
),
the output activates each time the specified distance is transversed, and stays
active for the specified time.
When an absolute distance is used for comparison (2
nd
data field set to
Ø
), the
output activates when the actual position is greater than the specified absolute
distance, and stays active for the specified time.
NOTE
The output activates only during motion; thus, issuing a
PSET
command to set the absolute
position counter to activate the output on position will not turn on the output until the next
motion occurs.
Example
Command Description
> OUTFEN1
Enable programmable output functions
> OUTFNC25-H
Set
OUT-A
(output #25) as output on position output for axis 1
> OUTFNC26-H
Set
OUT-B
(output #26) as output on position output for axis 2
> OUTPA1,Ø,+5ØØØØ,5Ø
Turn on
OUT-A
for 50 ms when the actual position is greater
than or equal to absolute po50,000
> OUTPB1,Ø,+24ØØØ,2ØØ
Turn on
OUT-B
for 200 ms when the actual position is greater
than or equal to absolute po24,000
Input Functions
The input functions are assigned with the
INFNCi-<a>c
command. The "
i
" represents the
number of the input (the 24 general purpose inputs are inputs 1 through 24, and
TRG-A
and
TRG-B
are inputs 25 and 26). The "<
a>
" represents the number of the axis, if required. The
"
c
" represents the letter designator of the function (
A
through
P
). For example, the
INFNC5-
2D
command configures output #5 to function as a stop input, stopping motion on axis #2
when activated.
NOTE
To activate the function of an input with the
INFNC
command, you must first enable the input
functions with the
INFEN1
command. Because the
INFEN1
command enables the drive fault
input, you should verify the fault active level (
DRFLVL
) is set properly.

Input Status
As shown below, you can use the
INFNC
command to determine the current function and state
(on or off) of one or all the inputs. The
TIN
command also reports the inputs' state, but in a
binary format in which the left-most bit represents input #1 and the right-most bit represents
input #26.
