13.1 Outline of common functions 

"Common functions" are executed according to the user's requirements, regardless of

buffer memory and flash ROM to 
the factory-set initial value. 

 

 

Execution data backup 
function 

This function writes the 
"execution data", currently being 
used for control, to the flash 
ROM. 

 

 

External I/O signal logic 
switching function 

This function switches I/O signal 
logic according to the equipment 
connected to the QD75. 
For the system in which drive unit 
READY with b-contact, upper 
limit switch, and lower limit switch 
are not used, the parameter logic 
setting can be controlled without 
wiring if it is changed to a 
"positive logic".

monitor function 

This function monitors the 
external I/O signal monitor 
information in the module's 
detailed information which can be 
displayed on the system monitor 
of GX Developer .

  For the QD75P /QD75D , this function is available in GX Developer (SW6D5C-GPPW-E or 

later). 
For the QD75P N/QD75D N, external I/O signals cannot be monitored on GX Developer. 
Use the system monitor of GX Works2.
