Limit Of Load Inertia Estimation - Delta ASD-B2-0121-B User Manual

Chapter 5 Trial Run and Tuning Procedure

5.5.5 Limit of Load Inertia Estimation

The accel. / decel. time for reaching 2000r/min must be below 1 second.
The rotation speed must be above 200r/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.
