(5) In-position range
Set the servo parameter "In-position range (PA10)" and the parameter of the
inverter "
Pr.426
In-position width
" to be matched. Otherwise, it may not
operate correctly.

When droop pulses have fallen
below the setting value, the in-
position signal turns ON.
(6) Optional data monitor setting
The following table shows data types that can be set.
Data type Name at FR-A700 series use
Effective load ratio Motor load factor
Load inertia moment ratio Load inertia ratio
Model loop gain
Position loop gain
Main circuit bus voltage
Converter output voltage
Encoder multiple revolution counter
Encoder multiple revolution counter
Position feedback
Position feedback
Encoder position within one revolution Encoder position within one revolution
POINT
When FR-A700 series is used, each data is delayed for "update delay time +
communication cycle" because of the update cycle of the inverter. The following
table shows the update delay time of each data.
