Chapter 11 Motion Control Instructions
11-407
When CAByPos_Ex and CAByPos1_Ex are set to TRUE after axis 1 and axis 2 are power on, Busy and
Active of CAByPos and CAByPos1 instructions change to TRUE.
After the NC_Ex variable changes to TRUE, NC_Bsy changes to TRUE, NC_Act changes to TRUE,
NC_Cur displays the number of the row in which the CNC file is being parsed currently. NC_Px, NC_Py,
NC_Pz, NC_Pa, NC_Pb, NC_Pc, NC_Pp and NC_Pq output the positions of axes respectively after the
CNC file is parsed in the current cycle.
CAByPos controls X axis to move according to the value of NC_Px which is parsed out and CAByPos1
controls Y axis to move according to the value of NC_Py which is parsed out.
After the program is executed, the Position/Time curve for the whole motion process is shown
as below.
