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 update
delay time for each data is shown in the table below.
Data type Update delay time of FR-A700 series
Motor load ratio 12.5ms
Position F/B 222µs
Encoder position within 1
revolution
222µs
Load inertia moment ratio 56ms or more (up to 2500ms)
Position loop gain 56ms or more (up to 2500ms)
Converter output voltage 9.888ms
