Detailed description2.4 Electronic gearbox (EG)Special functions: Axis Couplings and ESR (M3)Function Manual, 11/2006, 6FC5397-2BP10-2BA0 71Definition of an EG axis groupAn EG axis group is defined through the input of the following axis and at least one, but notmore than five, leading axis, each with the relevant coupling type:EGDEF(following axis, leading axis1, coupling type1, leading axis2, coupling type 2,...)The coupling type does not need to be the same for all leading axes and must beprogrammed separately for each individual leading axis.Coupling type:Evaluate actual value of leading axis: 0Evaluate setpoint of leading axis: 1The coupling factors are preset to zero when the EG axis group is defined. As such, thegroup has no effect on the following axis until it is activated. (See EGON, EGONSYN,EGONSYNE).Preconditions for defining an EG axis group:No existing axis coupling may already be defined for the following axis. (If necessary, anexisting axis must be deleted with EGDEL.)EGDEF triggers preprocessing stop with alarm.For an example of how to use the EG gearbox for gear hobbing, please see Chapter"Examples", "Electronic Gearbox for Gear Hobbing".EGDEFThe gearbox definition with EGDEF should also be used unaltered when one or moreleading axes affect the following axis via a curve table.The variant extended with the addition of non-linear coupling via curve tables is illustrated inan extended example in Chapter "Extended Example with non-linear Components".
