SINUMERIK 840Di sl/840D sl/840D Operating Manual HMI-Advanced (BAD) - 01/2008 Edition
Function
In "MDA" (Manual Data Automatic) mode, you can write part programs
block by block and execute them. You can transfer the required
motions as single part program blocks to the control using the
operator panel. The control processes the entered program blocks
when you press the "NC Start" key.
Caution
The same safety interlocks must be applied as used in fully automatic
operation. The same preconditions must be fulfilled as for fully
automatic operation.
The automatic functions (traverse blocks) are active in "MDA" mode.
The functions associated with "JOG" are active in submode "Teach-in"
and can be accessed via an MCP key. You can therefore create and
store a program in the input and manual modes by alternating
between "MDA" and "Teach-in".
You can use the editor to edit the program blocks in the MDA window.
You can view blocks that have already been executed by paging
upwards.
Blocks that have already been executed can only be edited in the
Reset state. Further blocks can be added with "Input".
Blocks can only be input and executed with the channel in the
"Channel Reset" or "Channel interrupted" state.
The program created in MDA mode can be saved in the part program
directory (MPF.DIR).
