Symbol
(Negative logic is selected by external I/O signal logic selection)
•Input the zero signal for machine OPR control.
Use the encoder's zero signal and so on.
B14 PG0
•Use this signal when "
OPR complete is input from an external device.
•The zero signal is detected at turning from OFF to ON.
B13 PG0 COM •Common for zero signal
•This signal is used for detecting the near-point dog during machine OPR
B10 DOG control.
•The near-point dog signal is detected at turning from OFF to ON.
•Input this signal from the limit switch, which is set to the stroke upper
B8 FLS limit position.
•Turning OFF this signal stops positioning.
•Input this signal from the limit switch, which is set to the stroke lower
B6 RLS limit position.
•Turning OFF this signal stops positioning.
B9
•Common for near-point dog signal, upper limit signal, and lower limit
B7 COM
signal
B5
•This signal is output during machine OPR control.
•The output time of the deviation counter clear is set in "
counter clear signal input time".
B12 CLEAR
•Use the drive unit that can reset the droop pulse amount in the internal
deviation counter when the QD72P3C3 turns this signal ON.
(Note) The deviation counter clear is a signal output by the QD72P3C3
during machine OPR control. It cannot output randomly.
CLEAR
B11 •Common for deviation counter clear
COM
•This signal is used to output command pulses to the open collector
B4 PULSE F compatible unit.
CW/CCW mode: CW, PULSE/SIGN mode: PULSE
•This signal is used to output command pulses to the open collector
B2 PULSE R compatible unit.
CW/CCW mode: CCW, PULSE/SIGN mode: SIGN
B3 PULSE
•Common for pulse output F and pulse output R
B1 COM
B20 CHA_24V •Phase A pulse input for 24V
B19 CHA_5V •Phase A pulse input for 5V
B18 CHA COM •Common for phase A pulse
B17 CHB_24V •Phase B pulse input for 24V
B16 CHB_5V •Phase B pulse input for 5V
B15 CHB COM •Common for phase B pulse
