For SMC_CNC_REF
Starting coordinates can be specified in PMC_NCDecoder when decoding is executed.
Variable declaration section:
//FB instances
NCDecoder : PMC_NCDecoder;
Interpolator2D : PMC_ Interpolator2D;
ReadSetPosition : SMC_ReadSetPosition //Read current value
//Variables
buf : ARRAY[0..10] OF SMC_GEOINFO; //Buffer for decoding
fSetXPosition : LREAL; //Current value on X-axis
fSetYPosition : LREAL; //Current value on Y-axis
bStart : BOOL; //Execution flag
Control section:
IF bStart THEN
ReadSetPosition(Axisx:=X_Drive,Enable:=TRUE, Position=>fSetXPosition)
ReadSetPosition(Axisy:=Y_Drive,Enable:=TRUE, Position=>fSetYPosition)
NCDecoder(nSizeOutQueue := SIZEOF(buf),pbyBufferOutQueue :=
ADR(buf),dXStartPosition:=fSetXPosition,dYStartPositon:=fSetYPosition,
ncprog := CNC_Table1,bExecute:=TRUE);
Interpolator2D(Axisx:=X_Drive,Axisy:=Y_Drive,bExecute:=TRUE,
poqDataIn:=NCDecoder.poqDataOut,dwIpoTime:=1000);
END_IF
● When operation is started, SMC_ReadSetPosition reads the current coordinates and
PMC_NCDecoder specifies the coordinates as starting coordinates.
● If the specified starting coordinates differ from the operation starting coordinates, there is a
risk that rapid movement may occur.
