26 Setting the Tool Entry Prohibited Range
518 IB-1501268-K
(1) The function of disabling movement in the prohibited area works while the tool is within the prohibited area of stored
stroke limit IB or IIB.
The function does not disable any movement within the permitted area (including the boundary).
(2) All the axes for which the function disables movement are indicated in the alarm guidance.
(3) If the tool is at the center of the prohibited area, as illustrated below, the distance to the permitted area in the
positive direction is equal to that in the negative direction. In this case the tool can move in both directions. Note that
when the direction that has the shorter distance to the permitted area is uniquely determined as a result of the tool
movement, the function will disable movement in all the directions except for the said direction.
(4) If this function is used together with the stored stroke limit function that does not support this function, the tool may
be allowed to move towards the prohibited area of the combined stored stroke limit function, as illustrated below. To
prevent this, it is recommended to set the ranges of stored stroke limit IB and IIB to be large enough.
(5) As illustrated below, when stored stroke limit IB and IIB are used together, and the tool enters the overlap of the two
prohibited areas, movement of the tool may be disabled. To prevent this, configure settings so that the prohibited
areas of stored stroke limit IB and IIB will not overlap with each other. (If the tool has entered both prohibited areas
due to an incorrect setting, disable stored stroke limit IIB to move the tool.)
