(7) External input signal
Set as the following to fetch the external input signal (FLS/RLS/DOG) via
FR-A700 series.
(a) Set the following items with MT Developer2
• When using Q173DSCPU/Q172DSCPU
Set "Amplifier input" for every axis with signal type in the servo external
signal parameter of servo data setting.
• When using Q173DCPU(-S1)/ Q172DCPU(-S1)
Set "Amplifier input valid" as the external signal input setting in the
"Amplifier setting" of system setting.
(b) Set the parameters of the inverter as below.
(Otherwise, each signal remains OFF.)
