Creating zero offset groups

A zero offset group defines the rules of producing a zero offset. This means that it describes the components of a specific zero offset data record. A zero offset group is defined in the NC program or by default in the channel parameters list [1]-4, in conjunction with a symbolic string. The utilization of symbolic strings is explained in chapter 15. It always takes three steps to activate a zero offset group:

Programming example

1st step:

Definition of a zero offset group in the NC program under the VERSCH_1 symbol string, for example:

N10 " VERSCH_1" = " V.G.NP[1].ALL = V.G.NP[2].ALL + V.G.NP[4].ALL"

or in channel parameters list[1]-4:

makro_def[0].symbol    VERSCH_1
makro_def[0].nc_code V.G.NP[1].ALL = V.G.NP[2].ALL + V.G.NP[4].ALL

2nd step:

Producing the zero offset (new assignment of the NPV1 data record):

N20 " VERSCH_1"

3rd step:

Selection of the zero offset (here: NPV1, i.e. G54):

N30 G54
