5.Note
- The multi-spindle control option is necessary to use this function.
- In the case of parameter SOV (No.3106#5) (the spindle override value is displayed)=1, 1st spindle speed override value is
displayed.
- During constant surface speed control, the spindle speed is overridden after it is clamped at the value specified in the
maximum spindle speed clamp command (G50S_ for T series and G92S_ for M series). So, please be careful because
the actual spindle speed may exceed the value specified in the spindle speed clamp command.
Parameter SOC (No.3708#5)(during constant surface speed control, the speed clamp is carried out after spindle speed
override) is disabled. Even if this parameter is set, above note is not changed.
But above limit to the spindle speed (No.3772,3802,3822,3850) can be applied to clamp the spindle speed.
- During this function, there is no function to fix the override to 100% during tapping cycle mode (G84,G74 for M series and
G84,G88 for T series) and thread cutting mode (G33 for M series and G32,G92,G76 for T series). So, please set an
override value by ladder as required.
- Parameter No.5131(setting chamfering angle in threading cycle) can not be used. Please set 0 to this parameter.
- Set an override value to 100% for spindles whose speeds are not specified override.
- The spindle override isn't effective in the spindle which is controlled spindle speed with PMC.
- On FANUC Series 21i- MODEL B, PMC- SB7 is necessary.
