Chapter 5 Trial Run and Tuning Procedure
5.6.5 Limit of Load Inertia Estimation
The accel. / decel. time for reaching 2000r/min must be below 1 second. The rotation
speed must be above 200 r/min. The load inertia must be 100 multiple or less of motor
inertia. The change of external force and the inertia ratio can not be too much. In Auto
Mode (P2-32 is set to 1), the measured load inertia value will be saved automatically and
memorized in P1-37 every 30 minutes. In Semi-Auto Mode, it will stop estimating the load
inertia after a period of continuous adjustment time when the system inertia becomes
stable. The measured load inertia value will be saved automatically and memorized in P1-
37 when load inertia estimation is stopped.
