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 starts processing the entered blocks when you press the
"Cycle 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 processed 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 be input and operated only with the channel in the
"Channel Reset" or "Channel interrupted" state.
The program created in MDI mode is saved in the "MPF" directory as
a part program (MPF).
