13.4.6 Response of EG at Power ON, RESET, mode change, block search

After Power ON there are no active couplings.
Active couplings are retained after reset and mode
change.
With block search, commands for switching, deleting
and defining the electronic gear are not executed or
retained, instead they are skipped.

13.4.7 The electronic gear's system variables

By means of the electronic gear's system variables,
the part program can determine the current states of
an EG axis grouping and react to them if required.
Additional notes
The system variables for the electronic gear are
listed in the Annex. They are characterized by
names beginning with:
$AA_EG_ ...
or
$VA_EG_ ...

13.5 Extended stopping and retract (as of SW 5)

Function
The "Extended stopping and retract" function ESR
provides a means to react flexibly to selective error
sources while preventing damage to the
workpiece.
"Extended stopping and retract" provides the
following three part reactions:
• "Extended stopping" (independent drive, SW 5)
is a time-delayed stop.
• "Retract" (independent of drive)
means "escaping" from the machining plane to a
safe retraction position. This means any risk of
collision between the tool and the workpiece is
avoided.
• "Generator operation" (independent of drive)
For the cases in which the energy of the DC link
is not sufficient for a safe retraction, generator
operation is possible.
