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 Unit
Number of
words
Number of communication
data points
Motor load ratio [%] 1 1
Position F/B [pulse] 2 0
Encoder position within 1 revolution [pulse] 2 0
Encoder Multi-revolution counter [rev] 1 0
Load inertia moment ratio [× 0.1 times] 1 1
Position loop gain [rad/s] 1 1
Converter output voltage [V] 1 1
Cumulative current value
[Position
command]
(Note-1)
2 0
(Note-1): The position command is the command unit set in the fixed parameter.
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 Update delay time of FR-A800 series
Motor load ratio 10ms
Position F/B 222µs
Encoder position within 1 revolution 222µs
Encoder Multi-revolution counter 222µs
Load inertia moment ratio 10ms
Position loop gain 10ms
Converter output voltage 5ms
(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.
