C5-17, C5-18: Motor Inertia, Load Inertia Ratio
C5-17 and C5-18 determine the ratio of the machine inertia to the inertia of the motor being used.
Example: Setting C5-18 to 2.0 reflects a load inertia that is twice the motor inertia.
These parameters are set automatically when Inertia Tuning and ASR Tuning are performed in CLV and CLV/PM control
modes.
