Inertia ratio
[%]
100
Sets inertia ratio for load.
Inertia ratio is considered 100 percent when
there is no load from the motor. Because
setting inertia ratio against load is an important
control parameter for the operation of the
servo, inertia ratio shall be set by calculating
load inertia by the machine system and rotor
inertia from the motor specification table.
Setting an accurate inertia ratio is crucial for
optimal servo operation.
