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.
