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.
Data type Update delay time of FR-A700 series
Effective load factor
12.5ms
Load inertia moment ratio
56ms or more (up to 2500ms)
Model loop gain
56ms or more (up to 2500ms)
Bus voltage
9.888ms
Encoder multiple revolution counter
222µs
Position feedback
222µs
Encoder single revolution position
222µs
