The details of each QD75 external device connection connector are shown below:
Pin No.
Signal name

Signal details
(Negative logic is selected by external I/O signal logic selection)
Manual pulse generator A
phase (PULSER A+)
Manual pulse generator B

—
• Input the pulse signal from the manual pulse generator A phase and B
phase.
• If the A phase leads the B phase, the positioning address will increase at the
rising and falling edges of each phase.
• If the B phase leads the A phase, the positioning address will decrease at the
rising and falling edges of each phase.

Zero signal (+5V)
(PG05)
1A9 1B9 2A9 2B9
• Input the zero signal for machine OPR.
Use the pulse encoder's zero signal and so on.
• Also use this signal when the machine OPR method is the stopper method
and the OPR complete is input from an external source.
• The zero signal is detected at turning from OFF to ON.

Upper limit signal (FLS)
1A1 1B1 2A1 2B1
• This signal is input from the limit switch installed at the upper limit position of
the stroke.
• Positioning will stop when this signal turns OFF.
• When OPR retry function is valid, this will be the upper limit for finding the
near-point dog signal.
Lower limit signal (RLS)
1A2 1B2 2A2 2B2
• This signal is input from the limit switch installed at the lower limit position of
the stroke.
• Positioning will stop when this signal turns OFF.
• When OPR retry function is valid, this will be the lower limit for finding the
near-point dog signal.
