•
Set the speed to estimate the load characteristic while the realtime autotuning is enabled.
•
The higher the set value is, the earlier the load characteristic change is followed, but the estimated
variation against the disturbance becomes greater.
•
The estimated results is updated in every 30 minutes and saved in EEPROM.
Explanation of Settings
For details on realtime autotuning, refer to 11-3 Realtime Autotuning on page 11-7.
•
Make detailed settings for the autotuning function, when 6: the customized mode is selected in the
Realtime Autotuning Mode Selection (3002 hex).
For the Realtime Autotuning Mode Selection (3002 hex), refer to Realtime Autotuning Mode
Selection on page 9-4.
