The Machine Commands Mode Window is located on the right of the Main Window (Fig. 7.1-G) and is the main window of the entire application program. The displayed software buttons activate the functions described below.
Please note that all the operations described for the principal axes are also valid for all auxiliary axes. The following
functions can also be activated with the software buttons; in particular, Homing with Shift+F1, Manual Movement with Shift+F2, Data Input Movement with Shift+F3 and Automatic with Shift+F4.
7.8.1 Homing
The type of homing is displayed next to the button, as selected from the HOMING SubMenu in the OPTIONS Menu, that is GLOBAL, CENTER, SINGLE, MANUAL. When you press the Start button, the selected homing is performed. GLOBAL performs an automatic homing of all axes. CENTER homes all the axes of the selected center. SINGLE homes automatically only the selected axis.
If MANUAL HOMING is active, when you select an axis (e.g. axis X) and you press Enter (or double click), the homing coordinate entry window is displayed (Fig. 7.13). Enter the required coordinate and press START, the display of the axis coordinate turns to the required value. In this case the axis makes no movement as this operation is performed only to define manually the actual position of the axis. The selected co-ordinates for manual homing of the axes are displayed in the information box shown in Fig. 7.1-L.

7.8.2 Manual movement
Activates the jog function of the axis (manual movement). To move the selected axis, use keys + and - of the keyboard on the machine, using if necessary also the fast jog key (see par. 1.3.1). The + key causes the movement of the axis in the direction set as positive. The - key causes the movement of the axis in the direction set as negative. When you select the required axis (e.g. axis X) and press Enter (or double click), the Jog Speed Setup Window is displayed. In this window, Low Speed indicates the speed of movements commanded by the -and + keys, -and High Speed indicates the speed of movements comm-anded with the High Jog key (Fig. 7.14).
The two above mentioned speeds, by default are assigned values which correspond to the machine data and are displayed in the information box shown in Fig. 7.1-L.
Changing these values does not alter themachine data.

CNI Controlli Numerici Industriali7.8.3 Movement data input
Activates the Single Step and Data Input Movement function (Fig. 7.1-M). There are three different ways to execute Data Input Movement; they they are described below:
1. Single Step
2. Data Input Movement 3. step
By Single Step we describe the possibility of editing one program line and execute it immediately afterwards. To take advantage of this function, write the program line in the corresponding data entry box located on the right of the information box. To execute the line entered, press the START key on the machine keyboard.
By Data Input Movement we describe the movement of the selected axis. The movement is determined by the assignment of the following parameters:
Target coordinate, or displacement from the current position of the axis,
Positioning speed.
The target coordinate of the selected axis can only be determined when the program line box (single step) is not displayed. To close it, select the box and press the ESC key. The target co-ordinate is displayed in the information box shown in Fig. 7.1-L and can be changed by opening the corresponding data entry window (Fig. 7.15). To open the window, press Enter (or double click) after selecting the required axis.
Figure 7.15: MDI Window
In this window, you can determine the target coordinate and the reference spindle for the coordinates and the po-sitioning speed. Press the SPINDLE button to access a table to assist with the selection of the spindle (Fig. 7.16), selected among those linked to the axis. Press the Start key on the machine keyboard to position the axis.
Lastly, a consideration for the stepmode. It is not necessary to press the ESC key to exit from the single step mode. When the single step mode is active, the movement of the selected axis is always possible by pressing either the + or - key of the machine keyboard. The + key moves the axis towards greater coordinate values. The - key moves the axis towards smaller coordinate values. The High Jog key can also be used if necessary (see par. 1.3.1). When you select the required axis and press Enter (or double click), the Step, Large Step and Speed data entry window is displayed (Fig. 7.17). Step and Speed default to the corresponding machine data values, while Large Step is given by the Step value multiplied by 10. Some of this information is also displayed in the Information Box.

7.8.4 Automatic
When this option is selected, a program can be chosen, run and controlled. If theA.P. WORKLISTis active, a work list can be chosen and executed. To perform these operations, several applications are made available, such as PROGRAM, WORKLIST, DEBUG. To execute a program without a work list, close theA.P. WORKLIST, select the required program, and press the START key on the machine keyboard. The name of the program selected is displayed in the Information Box. To execute a work list, open theA.P. WORKLIST, load the required work list file, and press the START key on the machine keyboard. The name of the selected work list is displayed in the Information Box. Programs or work lists memorized in a remote machine can also be executed if the remote connection has been activated. Further information on remote connection and DNC mechanisms are found in paragraph 7.12.
