Variant 3:
The EG axis group is selectively switched-in with synchronization and the approach mode
specified with:
EGONSYNE(FA,"block change mode",SynPosFA,approach
mode[,LAi,SynPosLAi,Zi,Ni])
Meaning
Variant 1:
FA
Block change mode:
LA1, ... LA5
Z1, ... Z5
N1, ... N5
Only the leading axes previously specified with the EGDEF command may be programmed in
the activation line. At least one leading axis must be programmed.
Variant 2:
FA
Block change mode:
[,LAi,SynPosLAi,Zi,Ni]
LA1, ... LA5
SynPosLAi
Z1, ... Z5
N1, ... N5
Only leading axes previously specified with the EGDEF command may be programmed in the
activation line. Through the programmed "Synchronized positions" for the following axis
(SynPosFA) and for the leading axes (SynPosLA), positions are defined for which the axis
