APPENDICES
(5) Optional data monitor setting
The following table shows data types that can be set.
Set the data so that the total number of communication points per axis is no more
than 6 points.
Data type
Motor load ratio
Position F/B
Encoder position within 1 revolution
Encoder Multi-revolution counter
Load inertia moment ratio
Position loop gain
Converter output voltage
Cumulative current value
POINT
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.
Data type
Motor load ratio
Position F/B
Encoder position within 1 revolution
Encoder Multi-revolution counter
Load inertia moment ratio
Position loop gain
Converter output voltage
(6) External input signal
Set as the following to fetch the external input signal (FLS/RLS/DOG) via
FR-A800 series.
(a) Set the following items with MT Developer2.
Set "Amplifier input" for every axis with signal type in the servo external
signal parameter of servo data setting.
(b) Refer to the instruction manual of FR-A800 series for parameter settings on
the inverter side.
