YASNAC PCNC I/O Signal Function Manual Chapter 6: Operation Support Functions
(e) MDI: Manual Data Input Mode
When the “MDI” input signal is “closed” with other inputs “open”, the CNC enters the
MDI mode. In this mode, operation using a part program entered by the manual data
input operation is enabled.
(f) MEM: Memory Mode Input
When the “MEM” input signal is “closed” with other inputs “open”, the CNC enters
the memory mode. In this mode, operation by using a part storage program stored in
the CNC part program memory is enabled.
(2) Operation Mode Output Signals
The operation mode output signals indiacte the present CNC mode.
(a) MAN: Manual Mode Ouput
This signal is output when the CNC is in any of the following states:
H (handle mode)
STP (manual step mode)
JOG (manual jog mode)
RT (rapid feed mode)
(b) AUTO: Automatic Mode Output
This signal is output when the CNC is in any of the following states:
TP (tape mode)
MEM (memory mode)
MDI (manual jog mode)
EDT (program edit mode)
Manual Mode Output Signal MAN #35010
Automatic Mode Output Signal AUTO #35011
