Connecting power cables
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.
Refer to "Apx-2 Calculating inertia moment“ (P.Apx-3) for the calculation of inertia moment.
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.
