data input operation mode input

When the MDI input contact is closed, and other mode input contacts are opened, the con-
trol enters the manual data input mode, and part programs will be written or the machine
will be operated through MDI.

(9) 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 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.

NOTE: The YASNAC i80L permits editing even if the machine is not in

the program edit mode. Therefore, the

i80L need not always

be placed in the program edit mode.

(2) operation Mode

Output

The control outputs the following signals to inform the current operation mode.

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.

This output is generated during editing operations (part program reading or checking, pun-

ching, stored program changing, or other editing operations).
