Manual Adjustment Of Friction Compensation - YASKAWA E-V Series User Manual

5.8.2 Manual Adjustment of Friction Compensation

Friction compensation rectifies the viscous friction change and regular load change.
The friction compensation function can be automatically adjusted with advanced autotuning (Fn201),
advanced autotuning by reference input (Fn202), or one-parameter tuning (Fn203). This section describes the
steps to follow if manual adjustment is required.
