(g) EDT: Program edit mode
When the EDT input contact is closed and other operation mode
input contacts are open, the control enters the program edit
mode, and it can store part programs into the memory, correct
and change them.
(2) Operation Mode Output
The control outputs the following signals to inform the current
ope-ration mode.
(a) AUT: Automatic operation mode output
This output signal is turned on when the control is in the T (tape
operation), MEM (memory operation), or MDI (manual data
input operation) mode.
(b) MAN: Manual operation mode output
This output signal is turned on when the control is in the H
(manual handle operation), S (manual step operation) or JOG
(manual jog) mode.
(c) EDTS: Editing output
This output signal is turned on when the control is in the EDT
(pro-gram editing) mode, and also performing and editing
operation (part program reading, collation, punching, and stored
progrm changing and other processing).

Notes :
1.When any operation-mode-inputexcept manual operation mode is
given during NC program operation in the memory operation
mode, the control stops the execution of the part program after the
execution of the current block. The some applies to the part
program operation in the tape and MDI mode.
2. When a mancrat-operation-mode-inputcontact is closed during the
execution of a part program in the memory operation mode, the
following changes take place.
i. Motion command
The current motion stops after deceleration, and the program is
interrupted. The remaining program can be restarted when the
automatic operation mode is turned on again and the cycle start
(SP) input contact is closed.
ii. M, S, T command
The sampling outputs (MF, SF, TF) and the M code outputs are
turned off, and the M, S, T command is regarded to have been
executed completely.
Even when the contol is returned to the automatic operation
mode, the interrupted M, S, T command is not resumed,
3. When an automatic operation mode or program editing mode
input contact is closed during motion in the manual operation
mode, the motion decelerates and stops.
4. When any of these operation mode input contacts is closed, that
mode becomes effective,
Under other input states, the previous operation mode remains
effective. When no operation-mode-input-contactsis closed after
the energization , or when two or more operation-mode-input-
contacts are closed, the control enters the manualjog mode.

during the tapping process in a part program, the
automatic operation mode is retained while the thread is
being cut.
