• Checking the Load Inertia ratio
Load inertia ratio gained in autotuning can be checked in Con-13,
SEt-66.
Load inertia ratio is calculated as the following,
Load Inertia
Load Inertia Ratio =
Motor Inertia
Displayed to the first decimal point.
* Refer to Table 7.3 for allowable load inertia in operation of each
motor in rated speed.
