5.5.5 Limit of Load Inertia Estimation

1. The accel. / decel. time for reaching 2000RPM must be below 1 second. The rotation speed must
be above 200RPM. 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.
2. The measured load inertia value will not be saved when the power is cut off. When re-apply the
power to the drive every time, the setting value of P1-37 is equal to the initial value of load inertia
value. But, when the Tuning Mode Settings of P2-32 is set from AutoMode #1 to AutoMode #2, the
measured inertia value will be memorized in P1-37 automatically.
