MDI
6 To stop or terminate MDI operation in midway through, follow the
steps below.
a.
Stopping MDI operation
Press the feed hold switch on the machine operator’s panel. The
feed hold LED goes on and the cycle start LED goes off. The
machine responds as follows:
(i) When the machine was moving, feed operation decelerates
and stops.
(ii) When dwell was being performed, dwell is stopped.
(iii) When M, S, or T was being executed, the operation is
stopped after M, S, or T is finished.
When the cycle start switch on the machine operator’s panel
is pressed, machine operation restarts.
b. Terminating MDI operation
Press the
RESET
key on the MDI panel.
Automatic operation is terminated and the reset state is entered.
When a reset is applied during movement, movement
decelerates then stops.
The previous explanation of how to execute and stop memory operation
also applies to MDI operation, except that in MDI operation, M30 does
not return control to the beginning of the program (M99 performs this
function).
Programs prepared in the
MDI mode will be erased in the following cases:
D In MDI operation, if M02, M30 or ER(%) is executed.
(If bit 6 (MER) of parameter No. 3203 is set to 1, however, the program
is erased when execution of the last block of the program is completed
by single–block operation.)
D In
MEMORY mode, if memory operation is performed.
D In EDIT mode, if any editing is performed.
