*1 If the item is set, the error "Continuous path control not possible" (error code: 516) or "New current value not possible"
(error code: 515) will occur at a start.
*2 Setting value invalid Use the initial value or a value within the setting range.
*3 Two control systems are available: the absolute (ABS) system and incremental (INC) system.
*4 Set the M code for the reference axis and the number of pitch for the linear interpolation axis.
Remark
It is recommended that the "positioning data" be set whenever possible with GX Works2. Execution by program uses many
programs and devices. The execution becomes complicated, and the scan times will increase.
