12.2 Software limits.
The CNC lets set the software limits on linear axes and on linearlike rotary axes. The software
limits set the travel limits for the axes to prevent the carriages from reaching the mechanical
hard stops. The carriages reach the hard stops when the reference point of the tool holder
is placed at the physical limits.
CNC behavior when an axis reaches the software limits.
In automatic mode, when programming a position where the reference point of the tool holder
is beyond the software limits, the CNC interrupts the execution and shows the pertinent error
message. The programmable positions of the axes depend on the dimensions of each tool.
In jog mode, when an axis reaches the software limits, the CNC interrupts the execution and
shows the pertinent error message. To take the axis to the work zone, access the JOG mode
and move the axis that overran the travel limit. The axis can only move in the direction that
places it within the limits.
Software limits applied by the CNC (first and second limits).
Each axis can have two active software limits, called first and second limit. Since each
software limit is defined by an upper and lower limit, each axis can have a total of two upper
limits and two lower limits. Of the each limit pair, (lower and upper), the CNC applies the most
restrictive one regardless of whether they belong to the first or to the second limit.
