62 8025/8030 CNC PROGRAMMING MANUAL
6.16. G47 - SINGLE BLOCK TREATMENT
G48 - CANCELLATION OF SINGLE BLOCK TREATMENT
As of the execution of function G47, the CNC executes all the blocks which come next as
if it were a single block. This single block treatment is carried out until it is cancelled by
means of the G48 function. In this way, with the G47 function active in the SINGLE
BLOCK operation, these will be executed in continuous cycle until the G48 function is
executed, i.e., the execution will not stop when a block is finished but will continue by
executing the following one.
In any operating mode, if execution is interrupted when the G47 function is active, the
CNC stops axis feed as well as the spindle. It will also stop axis feed when the FEED
HOLD input is activated, as long as machine parameter P610(1)=1.
With the G47 function active, the M.F.O. switch and the spindle speed variation keys will
be disenabled, the program being executed at 100% of the programmed F and S.
The G47 and G48 functions are MODAL. When the CNC is switched on, after executing
MO2, M30, Reset or Emergency, the CNC assumes the G48 function.
6.17. G49. PROGRAMMABLE FEEDRATE OVERRIDE
With G49 the programmed working feedrate F can be overridden.
The feedrate override Knob on the front panel will have no effect.
The programming format is: G49 K (1/120). 1/120 meaning the percentage value between
1% and 120% of the previously programmed F value.
Function G49 is modal, so it will remain active until another value is programmed or is
cancelled by programming: G49 K0 or simply: G49.
G49 will also be cancelled when M02, M30, RESET or EMERGENCY are executed.
G49 K must be programmed alone in a block.
