When FR-A800 series is used, each data is delayed for "update delay time + communication cycle" because
of the update cycle of the inverter. The update delay time for each data is shown in the table below.
External input signal
Set as the following to fetch the external input signal (FLS/RLS/DOG) via FR-A800 series.
■Setting in MT Developer2
Set "Amplifier input" for every axis with signal type in the external signal parameter of axis setting parameter.
■Parameter settings on the inverter side
Refer to the instruction manual of FR-A800 series for parameter settings on the inverter side.
