OPERATION
STARTING A UTOMATIC O PERATION
Before you can run a program, it must be loaded in the current memory. To select a program, push the LIST
PROG mode key. Use the cursor to find the desired program and then push SELECT PROG. The program list
includes the program name and the first comment. If the control was turned off while running, that program will
automatically be in current memory and selected.
If the machine has just powered up, you need to first push the POWER UP / RESTART key. This will initialize
all axes and the tool changer, display the Current Commands, and go to MEM mode with the control ready to
run. Pushing the CYCLE START button in the lower left of the control panel will begin execution.
To start a program other than at the beginning, scan to the block number using the down arrow or PAGE
DOWN until you reach the desired starting place. Push the MEM key and CYCLE START to begin. The
Program Restart function, selected from Setting 36, will change the way a program operates if you start from
other than the first block. The setting called Program restart îš“ONîš” will ensure that the correct tool and axis
positions are selected when you start from part way through a program.
Any errors in your program will cause an alarm and stop the running of the program. Typical alarms are travel
limits and missing I, J, and Q codes. Attempts to move outside of the limits of travel will also cause an alarm.
When cutting materials that produce hot chips, it is important to use coolant.
At any time that a program is running, the bottom left corner of the CRT will show RUNNING. If it does not show
this, the program has completed, has been stopped by the operator, or has been stopped by a fault condition.
PROGRAM R ESTART
Program Restart is designed to help the operator start a program from the middle while still properly interpreting
all of the preceding lines of the program. To use program restart, turn on setting 36, move the cursor pointer to
where you want to start (the restart point), and press Cycle Start. You do this by using the CURSOR up and
down keys in MEM mode. The control will begin "invisible" interpretation of the program from the beginning and
you will see the cursor move through the program. When it gets to the line you wanted to start on, the control
will establish all of the conditions that would normally have been true at the end of the previous line and then
execute the highlighted line and the rest of your program. Most program interpretation alarms which you might
have gotten in the invisible phase will not occur until after the line at your restart point is complete.
As an example, if the following program were to restart at the T2 line, the control would change to T1 and then
change to T2 before start axes motion. If the H and T agreement setting (15) was on, you would still not get an
alarm. The double tool change is probably the most difficult to understand. The control does that because it
insures that everything that must be true on the previous line is established and that means go tool 1. It then
executes the restart line which says go to tool 2
