6-17 Instantaneous Speed Observer Function
Outline of Operation
Estimating the motor speed using a load inertia increases responsiveness and reduces
vibration at stopping and improves the speed detection accuracy. This function can be used
for position control.
The instantaneous speed observer function can be used in the following situations.
Œ
When servo is ON
Œ
When there is no trouble with the motor's normal rotation
Œ
When realtime autotuning is disabled
