Conditions that interfere with the Load Characteristic Estimation function
• If the load inertia is small, i.e. less than 3 times the rotor inertia or large, i.e. the
applicable load inertia or more
• If the load inertia changes easily
• If the machine rigidity is extremely low
• If there is a non-linear element (play), such as a backlash
• If the speed continues at lower than 100 r/min
• If the acceleration/deceleration is 2,000 r/min/s or lower
• If the acceleration/deceleration torque is small compared with the unbalanced load
and the friction torque
• If the speed or torque oscillates due to the high gain or small effect of each filter.
