Friction Compensation
Friction compensation is used to compensate for viscous friction fluctuations and regular load
fluctuations.
You can automatically adjust friction compensation with autotuning without a host reference,
autotuning with a host reference, or custom tuning, or you can manually adjust it with the fol-
lowing procedure.
