3 COMMON PARAMETERS
(5) External signal input
Servo external signal (Upper stroke limit/Lower stroke limit/Stop signal/Proximity
dog) can be selected for every axis from the following methods.
(a) Q172DLX Servo external signals interface module use
• Q173DSCPU/Q172DSCPU
Select "Q172DLX signal" for every axis with signal type in the servo
external signal parameter of servo data setting, and set the module No.
and signal No.
• Q173DCPU(-S1)/Q172DSCPU(-S1)
Set the servo external signals interface module (Q172DLX) in the Motion
Slot Setting of the System Setting, and then set axis No. in the External
signal setting of the Detailed Setting.
(b) Servo amplifier input device use (Servo amplifier use only)
• Q173DSCPU/Q172DSCPU
Set "Amplifier input" for every axis with signal type in the servo external
signal parameter of servo data setting.
• Q173DCPU(-S1)/Q172DSCPU(-S1)
Set "Amplifier input valid" as the external signal input setting in the
"Amplifier setting" of system setting.
1) There are following restrictions to use.
• Stop signal (STOP) cannot be used.
• When the Q173DCPU(-S1)/Q172DSCPU(-S1) is used, count type
home position return or speed/position switching control cannot be
used depending on the operating system software's version. (Refer to
Section 1.5 for the software version that supports this function.)
• 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)
execute the high-accuracy control.
2) The correspondence of external signal and input device is shown below.
Upper stroke limit (FLS)
Lower stroke limit (RLS)
Proximity dog (DOG)
(Note): Refer to the "Servo Amplifier Instruction Manual" for pin configurations.
3) Set the external signal setting in the "Input Filter Setting".
(Note): The setting value set by "Input Filter Setting" of system setting is
valid even if the input filter setting is set by servo parameter
"Input filter setting (PD11)".
(c) Input device use
Select "Bit device" for every axis with signal type in the servo external signal
parameter of servo data setting, and set the device No.
