Function
With the "Teach-in" function, part programs (main programs and
subprograms) for motion sequences or simple workpieces can be
created, edited and executed by approaching and then storing
positions in combination with the "MDA" function.
There are two possible methods of writing programs with
"Teach-in" and "MDA":
1. Manual positioning
2. Manual input of coordinates and additional information
Both entry of blocks (input, delete, insert) and automatic insertion by
manual approach of positions are possible only at points that have not
yet been executed.
