G50 can be used to limit the maximum spindle speed. The control will not allow the spindle to exceed the S address value specified in the G50 command. This is used in constant surface feed mode (G96).

This G code will also limit the secondary spindle on DS-Series machines.

N1G50 S3000 (Spindle rpm will not exceed 3000 rpm) ; N2G97 M3 (Enter constant surface speed cancel, spindle on) ;
note: To cancel this command, use another G50 and specify the maximum spindle RPM for the machine.
