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.

Setting.”)
