13.4.2 Activate electronic gear

There are two variants for the activation command:
• Variant 1:
The EG axis grouping is activated selectively
without synchronization with:
EGON(FA, "Block change mode", LA1, Z1,
N1, LA2 , Z2, N2,..LA5, Z5, N5.)
Explanation
FA
Block change mode
LA1, ... LA5
Z1, ... Z5
N1, ... N5
It is only permissible to program the leading axes
which have previously been specified with EGDEF.
At least one leading axis must be programmed.
The positions of the leading axes and following axis
at the time of activation are saved as "synchronized
positions". The "synchronized positions" can be read
via system variable $AA_EG_SYN.
• Variant 2:
The EG axis grouping is activated selectively with
synchronization with:
EGONSYN(FA, "Block change mode", SynPosFA,[, LAi, SynPosLAi, Zi, Ni])
