P621(7) It is wrong, it should say: P621(7) The M06 function executes the M19 function (0=Yes, 1=No) MODIFICATIONS TO THE INSTALLATION MANUAL (REF. Feedback inputs for rotary axes, it should say: W (GP), Comparison table xii. [. . . ] The maximum length compensation values are: L+/-1000 mm or +/-39. 3699 inches K+/-32. 766 mm (1. 2900 inches) The call codes for length compensation are: G43 : Length compensation G44 : Cancellation of length compensation When G43 is programmed, the CNC compensates the length according to the value selected from the tool table (Txx. 00-Txx. 99). Length compensation is applied to the axis perpendicular to the principal plane. G17 : Length compensation on the Z axis G18 : Length compensation on the Y axis G19 : Length compensation on the X axis The tool length compensation will be applied on the 4th axis (W) or to the 5th axis (V) when appropriate, i. e. when the axis linked to it is not on the main plane. Function G43 is modal (persistent) and is cancelled by G44, G74, M02, M30, EMERGENCY or RESET. Length compensation can be used in conjunction with canned cycles, although in that case the precaution has to be taken of applying the compensation before the cycle starts. 8025/8030 CNC PROGRAMMING MANUAL 67 Example of tool length compensation It is supposed that the tool used is 4 mm shorter than the tool programmed. The tool number is T1. 1 (the value recorded in the tool table is L-4).

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 machineparameter 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. When the CNC is switched on, after executing MO2, M30, Reset or Emergency, the CNC assumes the G48 function. 6. 19. 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. [. . . ] The CNC considers the execution of the block concluded when all the involved axes have reached position. In other words, when all their "In-Position" outputs are high. If while executing a G05 in Automatic mode, you switch to Single Block mode, the CNC will execute this block in G07 and it will generate the "Brake" and "In-Position" signals at the end of the block. 3. 5. 3 MANUAL FEEDRATE OVERRIDE SWITCH When selecting any position between 4% and 120% of the %Feed area, the Fast/Slow sequence will be the one described earlier. When selecting the 2% position of the %Feed area, the CNC always applies the "Slow " feed. [. . . ]
