• When the "bStart" flag is set to TRUE, NCDecoder and Interpolator2D start being
executed.
•
PMC_NCDecoder and PMC_Interpolator2D must be executed at the same time.
• For dXStartPosition and dYStartPosition in PMC_NCDecoder, specify the respective
positions on the X-axis and Y-axis when interpolation control starts being executed. (For
details, refer to "11.5.11 Interpolation Operation Programming: Specifying the Starting
Coordinates".)
[Setting example 2] ST program example: SMC_OUTQUEUE type CNC table
G-code (SMC_OUTQUEUE): CNC_Table2
N01 G01 X10 Y10 F10 E1 E-1
Variable declaration section:
//FB instances
Interpolator2D : PMC_ Interpolator2D;
//Variables
bStart : BOOL; //Execution flag
● Explanation of declaration section
•
In Line 2, a function block to be used is defined by assigning an arbitrary name to it.
• In Line 4, a flag for starting execution is defined.
Control section:
IF bStart THEN
Interpolator2D(Axisx:=X_Drive,Axisy:=Y_Drive,bExecute:=TRUE,
poqDataIn:=ADR(CNC_Table2),dwIpoTime:=1000,);
END_IF
● Explanation of control section
•
When the "bStart" flag is set to TRUE, Interpolator2D starts being executed.
• For PMC_Interpolator2D, specify the address of the SMC_OUTQUEUE type CNC table
that has been created.
• In PMC_Interpolator2D, match the position at the start of operation and the current value.
(For details, refer to "11.5.11 Interpolation Operation Programming: Specifying the Starting
Coordinates".)
■
PMC_Interpolator3D (3-axis interpolation)
The function block executes 3-axis interpolation control according to the specified CNC table.
For the detailed specifications of the function block, refer to the GM1 Series Reference Manual
(Instruction).
