"Zero point" tab 1:

The current zero shift values for the axes within the interpolation group are displayed here. The parameters P54..P59 represent for the corresponding G code. As for the R parameters, the zero shift values can be edited from here.

Notice

Columns F & G (e.g. P54 F & P54 G) exist for historical reasons and are added for each parameter.

You can find further details of the effects in the interpreter description under zero shifts.
