6.8.2 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),
adv
anced autotuning by reference input (Fn202), or one-parameter tuning (Fn203). This section describes the
steps to follow if manual adjustment is required.
