Warning
If several block calls (FC 15, FC 16, FC 18) are programmed for the same axis/spindle in the
PLC user program, then the functions concerned must be interlocked by conditional calls in
the user program. The conditional call of a started block (parameter Start or Stop = TRUE)
must be called cyclically until the signal state of output parameter Active or InPos changes
from 1 to 0.
Declaration
FUNCTION FC 16: VOID //PART_AX
VAR_INPUT
Start: BOOL ;
AxisNo: INT ;
IC: BOOL ;
DC: BOOL
Minus: BOOL ;
Plus: BOOL ;
Pos: INT ;
FRate: REAL;
END_VAR
VAR_OUTPUT
InPos: BOOL ;
Active: BOOL ;
StartErr: BOOL ;
Error : BOOL ;
END_VAR
Description of formal parameters
The table below lists all formal parameters of the PART_AX function:
Signal I/O Type Value range Remarks
Start I Bool
AxisNo I Int 1 - 31 No. of axis to be traversed
IC I Bool = Absolute direction input
1 = Incremental direction input
DC I Bool = Predefined direction
= Shortest path
