Errors
An operation error is caused in the following cases; The error flag M8067 turns ON, and the error code is stored in
D8067.
• When the Xn data is not set in the ascending order in the data table (error code: K6706)
The data table is searched from the low-order side of device numbers in the data table in the operation.
Accordingly, even if only some Xn data is set in the ascending order in the data table, the instruction is executed
without operation error up to the area of the data table in which the Xn data is set in the ascending order.
• When
S
1
• When the value exceeds the 32-bit data range in the middle of operation (error code: K6706)
In this case, verify that the distance between points is not "65535" or more.
If the distance is "65535" or more, reduce the distance between points.

When coordinates are specified using three points in this
way, the output value can be set to an intermediate value.
R9 K200
In this example, the output value (intermediate value) is
specified by the Y coordinate of the point 5.
R10 K70
If the X coordinate is the same at three points or more,
the value at the second point is also output.
R11 K200
R12 K250
R13 K250
R14 K90
R15 K350
When coordinates are specified using two points in this
R16 K90
way, the output value is the Y coordinate at the next point.
In this example, the output value is specified by the Y
R17 K350
coordinate of the point 9.
R18 K30
R19 K400
R20 K7
