8.16.6 Related settings of unit conversion
Set the feed value (screw lead) of external encoder (optical scale) for one motor revolution by Pt20A. Set
linear unit length (resolution) of external encoder by Pt20B. If reduction gearbox is used, set gear ratio at
motor side (full-closed loop) by Pt20C and gear ratio at load side (full-closed loop) by Pt20D.
