19 Safety Functions
limit data of coordinates specified for that axis will limit the movement by stopping the tip of the tool at the limit. If, however, the compensation is not set up, the reference point of the tool holder will not be allowed into the prohibited area. It is advisable to set the border of the forbidden area at the axis of the tool for the longest one.
–Programable stroke check function is not available for the additional axes.
–Instructions G22, G23 have to be specified in independent blocks.
–Programable stroke check function will be effective after reference point return.
–If the machine enters a prohibited area after
–If an axis reaches the border of the prohibited area in motion, it can be removed from it by manual movement (in one of the manual modes).
–The entire space is allowed if X=I, Y=J, Z=K and E=0.
–The entire space is prohibited if X=I, Y=J, Z=K and E=1.
–If the area is prohibited internally, and the axes reach the prohibited area or a border thereof, the control will return the error message 1400 INTERNALLY FORBIDDEN AREA.
–If the area is prohibited externally, and the axes reach the prohibited area or a border thereof, the control will return the error message FORBIDDEN AREA t+ or FORBIDDEN AREA t– where t is the name of axis.
19.2 Parametric Overtravel Positions
Using the parameters of the control, the
SParametric overtravel function is only performed by the control after reference
point has been returned.
SThe parametric overtravel function will
prohibit always an external area.
S The areas of programmed stroke check and that of overtravel functions may overlap.
