Save position values:
Enter the additional functions (e.g. feedrates, auxiliary functions, etc.)
in the program (if permitted).
Using MDA file functions, you can save the MDA program in the "Part
programs" directory (MPF.DIR).
Using the edit functions of the vertical softkeys, you can execute the
following program block functions: Overwrite, Select, Copy, Paste,
Delete, Find, Find Next and Position.
When you switch to "MDA" mode and press "NC Start", the
corresponding traversing motions and additional function entries are
executed as program blocks. While the program is being processed,
the blocks traversed by the NC are displayed in the "Current block"
window.
2. Manual input of coordinates
Sequence of operations
"MDA" mode is selected in the "Machine" operating area.
Save position values/additional functions:
Transfer the coordinates of the traversing positions plus
any additional functions (preparatory functions, auxiliary functions,
etc.) to the program by entering them in the "MDA program" window.
Additional information
• Any change to the work offset will cause the axis to carry out
compensating movements when you press NC Start.
• In the case of G64, the end point response will differ when the part
program is executed in "Automatic" mode.
• All the G functions can be used.
• When using special kinematics or robots, the positions of the STAT
machine and rotary axis TU are displayed in addition to the
positions in the workpiece coordinate system.
