the function key labled POS then the soft key ABS. The displayed coordinate values represent the relationship between the Workpiece Zero and the Machine Zero (HOME). When the machine is HOME, press the soft key OPRT, then press ORIGIN and then press ALLEXE to zero each of the coordinate axes.
By pressing the soft keys, other display screens can be activated. For instance, when we press the button ABS (which corresponds to position), the digital counter appears on the screen for the X and Z axes, which is the absolute coordinate system for a given workpiece (for milling machines X, Y, and Z will be displayed). The position (POS) function is assigned four display screens and can be found by pressing the soft keys labeled; ABS, REL, ALL and OPRT. The first screen corresponds to a position change in the ABSOLUTE (ABS) system for X, Z, as illustrated. The second screen RELATIVE (REL) corresponds to position changes in the incremental system, U and W (for milling machines X, Y, and Z). The third, ALL gives representation of all four of the displays simultaneously on one screen as shown in Figure 32.
The values listed in the readout for MACHINE represent the distance from Machine Home position.
The DISTANCE TO GO readout is the most significant part of the third display. The coordinates in this quarter of the display of the screen correspond to the path that will be followed by the tool in order to complete the execution of a given block of information while under automatic operation.
Example:
N20G00Z0.
N22G01Z-12.000F.015

Figure 33 Program Library Screen
When block N22 is first read by the control, the value Z-12.000 will appear under DISTANCE TO GO readout in the lower right corner of the screen. After moving a distance of 1 inch, the value of coordinate Z changes to Z-11.000, and so on. The other displays, “ABSOLUTE” and “RELATIVE” correspond to the first two display screens, but this time they are smaller so that all four may fit on one screen. All of the displays may be changed to read in millimeters, with respect to Machine Zero, by changing a machine parameter or by using a G-Code in the program.
A Program is Loaded From Memory
The program may be in the program directory but not activated for automatic operation. Follow these steps to activate a program.
1. Press the EDIT button to enter the EDIT mode.
2. Press the PROG function key.
3. Either the program contents or program file directory will be displayed.
4. Press the OPRT soft key.
5. Press the rightmost (continuous-menu key) soft key.
6. Use the keypad to enter the desired program number preceded by the letter address O.
7. Press the FSRH (forward search) and the EXEC soft keys.
The program will now be in the active status and ready to use for automatic operation.
An NC Program is Loaded Into Memory
Follow the steps below to load a program into the controller from an NC tape. Be sure that the input device is ready for reading (tape entry to tape reader if used).
1. Press the EDIT button on the operator’s panel to enter the Edit mode.
2. Press the PROG function key.
3. Either the program contents or program file directory will be displayed.
4. Press the OPRT soft key.
5. Press the rightmost (continuous-menu key) soft key.
6. Use the keypad to enter the desired program number to load preceded by the letter address O.
7. Press the READ soft key and then the EXEC soft key.
The program will be loaded into the controller’s memory.
A Program is Saved to an Offline Location
For example; an NC Tape, Floppy disc, PCMIA card, or PC hard disk connected via RS232.
Follow the steps below to save a program to an NC tape.
Be sure that the output device is ready for output.
If the NC tape output is EIA/ISO, it needs to be specified by using a parameter.
1. Press the EDIT button on the operator’s panel to enter the EDIT mode.
2. Press PROG function key.
Either the program contents or program file directory will be displayed.
3. Press the OPRT soft key.
4. Press the rightmost (continuous-menu key) soft key.
5. Use the keypad to enter the desired program number to save preceded by the letter address O.
6. To save all programs stored in memory Press –9999.
7. To save multiple programs at one time enter their program numbers separated by a coma i.e.: O1234, O1235.
8. Press the PUNCH and then EXEC soft keys.
The program will be saved to the offline location media.
A Program is Deleted From Memory
To delete a program for the controller memory, follow these steps:
1. Enter the EDIT mode.
2. Press the PRGRM soft key.
The program directory will be displayed.
3. Press the OPRT soft key.
The screen with soft keys labeled F SRH, READ, PUNCH, DELETE and OPRT will be displayed.
The program directory is displayed only while in the EDIT mode.
4. Press the DELETE soft key.
5. Enter the program file number (preceded by the letter address O) you wish to delete.
6. Press the EXEC soft key.
The file is deleted.
To delete all programs from memory use steps one through three, and then the following steps in place of the last three steps as above:
Caution: Be sure the program files you are deleting are backed up prior to executing these steps because they will not be recoverable!
O–9999
