(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.

(6) Optional data monitor setting
The following table shows data types that can be set.
Effective load ratio
Load inertia moment ratio
Model loop gain
Main circuit bus voltage
Encoder multiple revolution counter
Position feedback
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.
