Diher frequency and ampliude are sofware selecable; he ampliude is auomaically reduced a high reference values (high regulaed flow / cylinder speed) o avoid possible insabiliy. ower frequency and higher ampliude reduce hyseresis bu also reduce he regulaion sabiliy. In some applicaion his can lead o vibraion and noise: righ seing usually depends on sysem seup.
