6.3.3.2 ZERO OFFSET LOADING (G51.....G60)
In order to use these functions, the internal CNC table must be set as zero offset table,
"P60(5)=1".
To see how to access this table, refer to the chapter on "AUX MODE" described
earlier in this manual.
Table address 1 corresponds to function G51, 2 to G52 and so on up to address 10
which corresponds to G60.
Functions G51, G52, G53, G54, G55, G56, G57, G58, G59 and G60 must be
programmed alone in the block and are incompatible with G92.
Their programming format is: G51 ... G60 X Y
The X and Y values indicate the distance from Machine Reference Zero (home)
where the part zero is to be set.
When executing one of these functions: G51, G52, G53, G54, G55, G56, G57, G58,
G59, G60, the CNC loads the new XY values at its corresponding table address.
6.3.3.3 ZERO OFFSET SELECTION (T1 ... T10)
To select a particular zero offset, use the "T" function.
The CNC cancels the previous zero offset and 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.
Example. G52 X100 Y50 Loads the table with X100 Y50
T2 Selects zero offset T2. The new part zero is at X100
Y50 from home.
This type of programmable zero offsets are very useful for repetitive operations to be
performed at different positions along the axes.
Attention:
"T0" cancels the previously active zero offset and does not apply a new
one. Therefore, the new part zero will coincide with the Machine Reference
Zero (home).
