FHA-C mini series selection
Allowable load inertia moment
To achieve high accuracy and performance, select a FHA-C mini series actuator where the allowable
load inertia moment (reference value) specified for the applicable model No. is not exceeded.
For the calculation of inertia moment, refer to [Apx-2 Calculating inertia moment] (PApx-3).
When temporarily selecting an actuator, make certain that the inertia moment and rotation speed do
not exceed the allowable values shown in the table below.
