Direct Drive Motor Specifications and Instruction Manual
8 Servo Adjustment
Load inertia ratio display
Perform the measurement referring to the section "(1) Measuring unbalance torque and frictional torque" of
"Improvement of protrusion at quadrant changeover" in Instruction Manual of each drive unit, 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.
