4 POSITIONING DEDICATED SIGNALS
(10) DOG/CHANGE signal (M2414+20n)
(a) This signal turns on/off by the proximity dog input (DOG) of the Q172DLX/
servo amplifier/input (DI) of built-in interface in Motion CPU
device
QDS
This signal turns on/off by the speed/position switching input (CHANGE) of
the Q172DLX/proximity dog input (DOG) of servo amplifier/input (DI) of
built-in interface in Motion CPU
switching control in the real mode.
(There is no CHANGE signal in the servo amplifier.)
(b) The state of the speed/position switching input (CHANGE) when the
CHANGE signal is ON/OFF is shown below.
1) Q172DLX use
DOG/CHANGE signal : ON
DOG/CHANGE
2) Servo amplifier input use
DOG signal : ON

4) Bit device use
The set bit device is the DOG/CHANGE signal.
(Note-1): Refer to the "Q173D(S)CPU/Q172D(S)CPU Motion controller Programming Manual
(COMMON)" for an external signal and bit device.
(Note-2): When using the Q173DCPU(-S1)/Q172DCPU(-S1), the external input signal (DOG)
of servo amplifier can also be used in the speed/position switching control. (Refer to
Section 1.4 for the software version that supports this function.)
(Note-3): Refer to the "Q173D(S)CPU/Q172D(S)CPU Motion controller User's Manual" for a
pin configuration.
(Note-4): Refer to the "Servo Amplifier Instruction Manual" for a pin configuration.
