Memory Operation or Auto Mode

Programs are registered in memory in advance. When one on these programs is
selected and the cycle start switch on the machine operator’s panel is pressed,
automatic operation starts, and the cycle start LED goes on.
When the feed hold switch in the machine operator’s panel is pressed during automatic
operation, this operation is stopped temporarily. When the cycle start switch is pressed
again, automatic operation is restarted.
When the RESET key on the MDI panel is pressed, automatic operation terminates and
the reset state is entered.
To complete this operation follow the next procedure:
1. Press the MEMORY (AUTO) mode selection switch.
2. Select the program from the registered programs doing the following steps:
• Press PROG to display the program screen.
• Press “+” soft key.
• Press “DIR” soft key and the program library will be displayed.
• Enter a program number using the numeric keys.
• Press the O SRH soft key.
3. Press the cycle start switch on the machine operator’s panel. Automatic operation
starts, and the cycle start LED goes on. When automatic operation terminates, the
cycle start LED goes off.
4. To stop or cancel memory operation midway through, follow the steps below:
• Stopping memory 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:
When the machine was moving, feed operation decelerates and stops.
When dwell was being performed, dwell is stopped.
When M, S, or T was being executed, the operation stopped after M, S, or T is finished.
• Terminating memory 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.

FADAL AUTOMATIC OPERATION MODES " MDI "

AUTOMATIC OPERATION MODES
" MDI " OPERATION MODE
In the MDI mode, a program consisting of up to 10 lines can be created in the same
format as normal programs and executed from the MDI panel. MDI operation is used for
simple test operations.
In order to complete this operation, follow the next procedure:
1. Press the MDI mode selection switch.
2. Press the PROG function key on the MDI panel to select the program screen.
3. Prepare a program to be executed by an operation similar to normal program editing.
M30, specified in the last block can return control to the beginning of the program
after operation ends. Word insertion, modification, deletion, word search,
address search, and program search are available for programs created in the MDI
mode.
4. To entirely erase created program in the MDI mode, use one of the following methods:
• Enter address, and then press the DELETE key on the MDI panel.
• Alternatively, press the RESET key.
5. To execute a program, set the cursor on the head of the program. Push CYCLE
START button on the operator’s panel. By this selection, the prepared program will
start. When the program end (M02, M30) or ER (%) is executed, the program will
be erased and the operation will end. By command of M30, control returns to the
head of the prepared program.
6. To stop or terminate MDI operation in midway through, follow the next steps:
• Stop 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.
• Terminate 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.
