DOG/CHANGE signal of Q172DLX and external
input signal (DOG) of servo amplifier can be used.
DOG/CHANGE signal of Q172DLX can be used.
POINT
The variation for ON/OFF timing of the external input signal (DOG) of servo
amplifier may occur according to the input filter setting value of external signal input
setting.
Review the input filter setting value compatible with the applications.
Use the Q172DLX to execute the high-accuracy control.
