8.6.8 Less Deviation Control
Less Deviation Control can provide shorter settling times and lower locus tracking errors by reducing the
position error as much as possible for the position control mode. There are two kinds of Less deviation control:
Basic Less deviation and Less Deviation control with reference filter. Operation can be adjusted easily with
utility function Fn015 (One-parameter Tuning for Less Deviation Control.) If higher performance operation is
required, the settings can be fine-tuned with the parameters.
