26.2.9 Behavior in Prohibited Area

26.2.9.1 Stored stroke limits I, IC, and II

When the tool has entered the prohibited area of stored stroke limit I, IC, or II, an operation error (M01 0007) occurs.
When the operation error occurs, only the axis that is within the prohibited range is prevented from moving away from the
permitted area.
In the example below, the X coordinate of the current position is within the prohibited range. So the movement in the X(-
) direction is disabled because the direction is not towards the permitted area.
The Y coordinate of the current position is within the permitted range. So the movement in the Y direction is permitted
within the permitted range even though the tool is inside of the prohibited area.
Movable
(Because Y axis is within
the permitted range)
Not movable
(Because the direction is
away from the permitted
area, which will cause an
operation error (M01 0007
X))

26.2.9.2 Stored stroke limits IB and IIB

For stored stroke limits IB and IIB, movement of the tool within the prohibited area can be disabled through the
parameter "#1711 cfg11/bit1" (disabling movement in prohibited area of stored stroke limit IB/IIB).
When this parameter is on, each axis is allowed to move only in the direction that has the shorter distance to the
permitted area. When an attempt is made to move an axis in the direction that has the longer distance to the permitted
area, an operation error (M01 0007) is issued, which disables the movement.
The alarm can be canceled through NC reset or by moving the axis in the direction that has the shorter distance to the
permitted area. The function of disabling movement in the prohibited area is supported by stored stroke limits IB and IIB.
The function does not apply to the prohibited area of stored stroke limit I, IC or II.
