MEM Memory operation mode input
When the MEM input contact is closed, and other mode input contacts are opened, the
control enters the memory operation mode, and the machine will be controlled by part
programs stored in the memory.
(h) EDT Program edit mode
When the EDT input contact is closed with the other operation mode input contacts are
opened, the control mode indicator shows the program edit mode.
However, it is possible
to store part programs into memory, correct them, and change them in any mode other than
TP or MDI.
operation Mode Output
The control outputs the following signals to inform the current operation mode.
(a) AUTO Automatic operation mode output
This output is generated when the control is in the TP (tape operation), MEM (memory op-
eration), MDI (manual data input operation), or EDT (program edit) mode.
(b) MAN Manual operation mode output
This output is generated when the control is in the H (manual handle operation), STP (manu-
al step operation), JOG (manual jog), or RT (manual rapid traverse) mode.
(c) EDTS Editing output
This output is generated during editing operations (part program reading or checking, pun-
ching, stored program changing, or other editing operations).

NOTE
1. When any operation mode input except manual operation mode is given during NC pro-
gram operation in the memory operation mode, the control stops the execution of the part pro-
gram after the execution of the current block.
The same applies to the part program operation
in the tape and MDI modes.
2. When a manual operation mode input contact is closed during the execution of a part pro-
gram in the memory operation mode, the following changes take place.
