6 POSITIONING CONTROL
REMARK
(Note): "The external CHANGE signal input from external source" is inputted to
CHANGE of signal type set in speed/position switching signal from external
source. When "normally open contact input" is set, CHANGE input occurs at
the CHANGE signal on, and when "normally closed contact input" is set,
CHANGE input occurs at the CHANGE signal off. (Refer to the
"Q173D(S)CPU/Q172D(S)CPU Motion controller User's Manual".)
The signal types that can be used with speed/position switching signal are
shown below.
Signal type
CHANGE signal of Q172DLX
External input signal (DOG) of servo
(Note-1)
amplifier
Built-in interface in Motion CPU (DI)
Bit device
(Note-1): 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 or built-in interface in Motion CPU (DI) to execute the high-accuracy
control.
