Graphical Speed

Ever since the very first Haas control was built, the system has been capable of providing a graphical simulation for the user's programs. This was easily activated by pressing the MEM button to put the control into Memory mode and then pressing SETNG/GRAPH key to enter the Graphics display. At this point, the user could then select F2 for the Zoom function using PAGE UP or PAGE DOWN to control the level of zoom. Alternatively, the user can press F3 key to change the position display, or the F4 key to display the current program and then pressing Cycle Start commences the 'running' of the program in the graphics display.

The Haas graphics system not only provides a graphical representation of the current program, but tests the program at the same time - looking for missing feedrates, syntax errors in the code and so on.

More recently, Haas controls have included the capability to alter the speed at which the graphic simulation is run, thus allowing the user to review slowly the particular area of concern before running through other sections at a much higher speed. The F3 and F4 buttons on these newer controls provide the speed control, whilst the functions previously associated with them (as above) are no longer required, as the program and positions are displayed permanently in graphics mode.
