DOK-MTC200-NC**PRO*V17-ANW1-EN-P
Notes:
•
The instruction concerned is executed immediately in the NC blocks in
which the user writes a modal instruction using MODF_ON.
•
The MODF_OFF instruction de-activates the modal instruction in the
block in which it is programmed.
•
It must be noted that the modal function (such as MODF_ON(RD 2))
does not have an effect on blocks without axis movements (i.e. without
feed axes). This is also true for contours that were created in the graphi-
cal editor and were saved as function block in the NC program.
