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 the 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 is outside the data table (error code: K6706)
• When the value exceeds the 32-bit data range in the middle of operation (error code: K6706)
In this case, check whether the distance between points is not “65535” or more.
If the distance is “65535” or more, reduce the distance between points.
Program example
In the program example shown below, the value input to D0 is processed by scaling based on the conversion
table for scaling set in R0 and later, and output to D10.
