COMPLEMENTARY
FUNCTIONS
6.4.3 TOOL NUMBER "T"
In order to use this function, it is necessary to set the internal CNC table as a tool table,
machine parameter "P60(5)=0".
To see how to access this table, refer to the chapter on "AUX MODE" described
earlier in this manual.
Every time a "T" function is executed, the CNC assumes the XY values indicated on
the table and applies the corresponding tool length compensation to each axis.
If "T0" is programmed, the CNC applies no compensation and it cancels any one that
may be active at the time.
Also, if machine parameter "P61(5)=0", every time a "T" function is executed, pins
20 through 27 of connector I/O1 show the BCD code of the selected tool and pin 4
of connector I/O2 outputs a "T Strobe".
6.4.4 ZERO OFFSET "T"
In order to use this function, the internal CNC table must be set as a zero offset table,
machine parameter "P60(5)=1".
Every time a "T" function is executed, the CNC cancels the zero offset currently active
and it applies the new one.
The new part zero will be located at a distance from home set by the XY values of
the corresponding table address.
This type of programmable zero offsets are very useful for repetitive operations to be
performed at different positions along the axes.
6.4.5 MISCELLANEOUS (AUXILIARY) "M" FUNCTION
After the "M" code, indicate the number of the miscellaneous function to be executed.
There are 100 different miscellaneous functions (M00 through M99).
Up to 4 M functions may be programmed in a block and they must be separated by
a period (M03.18.27).
When the new spindle speed requires a range change, the CNC automatically executes
the corresponding M function: M41, M42, M43 or M44. Therefore, when a block
contains an "S" code which implies a range change, only up to 3 more "M" functions
may be programmed.
Functions M41, M42, M43 and M44 cannot be programmed by the machine operator.
The M functions are executed at the beginning of the block except M00, M01 and
M30 which are the last ones to be executed in the block.
When more than one "M" function has been programmed in a block, the CNC executes
them in the order they are programmed.
