When converting this to data for controlling the motor, it is controlled by setting it from "0.00" to "015.00"mm.

It is actually composed of 16Bit, but the actual number of bits used can control 15.00mm even if only 11Bit is used, but 16Bit is used due to the structure of the data.

As described above, the XY axis control is moved from address 00001000h to the maximum length of stitch 16.00mm in units of 0.01mm on the Y axis according to the first ASCII code value, and in units of 0.01mm on the X axis according to the second 2 bytes of ASCII code value. It is controlled to move up to the maximum length of stitch 16.00mm.
