Rieter’s AC SERVOcombi upgrade package — designed to improve output on earlier-generation
autoleveler draw frames with DC servo motors — features an updated, maintenance-free servo motor;
digital control unit that processes signals in real time; quiet operation; high dynamics; and
homogeneous control behavior. Electronic control using the G90 motor brake further reduces
maintenance time.
