Warning
If several block calls (FC 18) have been 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.
