 For linear axis
[When uniform assignment is applied]
Special operation of linear axis in uniform assignment
Shifting from position where
more than one station distance
away from the both stroke ends
is not available.

distance
ST1
When starting within one
station from the stroke ends,
positioning will be carried out
to the first station.
[When arbitrary coordinate assignment is applied]
Special operation of linear axis in arbitrary coordinate assignment
ST1
When starting from outside of
the stroke range in direction
toward the stroke range,
positioning will be carried out
to the first station.
Operation with arbitrary coordinate designation
Positioning is carried out to an arbitrary position other than stations by directly commanding the positioning coordinates from
the PLC.
Set the coordinates as the control command position (R8054/R8055 for the 1st axis).
Command increment and command range depend on the "#1005 plcunit" setting.
#1005 plcunit setting value
B 0.001 (° or mm)
C 0.0001 (° or mm)
D 0.00001 (° or mm)
E 0.000001 (° or mm)
Note
(1) Inch/metric command is enabled by the "#1040 M_inch" setting.
When starting from outside of
the "near range", positioning
will be carried out to the nearest
station in designated direction.

When starting from inside of the
"near range", positioning will be
