[Learning mode]
1) During Learning, you must not change velocity over-ride. However, when you really execute a program first,
you need to execute that program under over-ride down. In this case, you can invalidate Learning control
temporarily. You should push soft-key
t [INVALID] on Monitor screen. We plan to develop function of
Learning invalidity from an outside signal.
2) When you create Learning data newly, you must clear Leaning data on a later Current data screen.
3) Please regard an aim to repeat a program as about five times.
4) When you judge a work to have achieved required precision by observing position error or measuring a
work precision, you store current Leaning data to CNC Flash memory (named current backup data), or
Memory card, or Personal computer on Current data screen. Current backup data can be loaded
automatically at power supply on.
(Note) Current Leaning data is stored in volatile memory area. Therefore Learning data disappear if power
supply off.
Refer to 6. Screen of Learning Control for Parts cutting.
[Product mode]
1) When you switch Learning mode and Product mode, you push soft-key r [LEARNING] or s [PRODUCT]
on Monitor screen. We plan to develop function of Learning mode switching from an outside signal.
2) When you loaded Learning data on Current backup screen, you should identify the date and time, and a
program number by all means.
3) When you mass-produce a work by the Learning data which you already learned, you should be machining
works of the same precision. In addition, Learning data is not updated in Product mode. If you want to cope
with time change, it is necessary to continue Learning the latest state in Learning mode.
Caution
If Learning data does not correspond with cutting program, there is a possibility of unexpected
move. Therefore you must identify correspondence of a cutting program as Learning data.
