KEY INPUT FROM PMC (EXTERNAL KEY INPUT)
When the PMC inputs the code signal corresponding to a key on the MDI
panel to the CNC, the code signal can be input in the same way as with
actual operation of the key on the MDI panel. For example, this function
is usable in the following case:
After allowing to travel the tool at an arbitrary machining position by
using the playback function, when to store its positions as the program
command, X, Y, Z, <SHIFT>, etc. must be input via key operations.
However, these operations can be realized simply by depressing a switch
on the operator’s panel at the machine side.
When the switch is pressed, the PMC inputs code signals corresponding
to keys X, Y, Z, and <SHIFT> to the CNC. This produces the same results
as with actual key operations.
