• 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.

• 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.
• Output the positioning pulses and pulse sign for the differential driver output
system compatible drive unit.
(QD75D N/QD75D only)
• Output the positioning pulses and pulse sign for the open collector output
system compatible drive unit.
(QD75P N/QD75P only)
• 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.
• 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.
