5.2 Gain Adjustment
Load inertia ratio display
Perform the measurement in the section "Measuring unbalance torque and frictional torque", and set a torque offset
(SV032) and frictional torque (SV045).
When an acceleration/deceleration operation is executed with the setting of SV035/bitF=1, an estimated load inertia
ratio will be displayed in "load inertia ratio " on the drive monitor screen.
