System variables of the electronic gear
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.
The system variables of the electronic gearbox are designated as follows:
$AA_EG_ ...
or
$VA_EG_ ...

9.4.3 Switching-in the electronic gearbox (EGOFS, EGOFC)
Function
There are 3 different ways to switch-out an active EG axis group.
Programming
Version 1:
Syntax Description
EGOFS(following axis)
The electronic gear is deactivated. The following axis is
braked to a standstill. This call triggers a preprocessing
stop.
Version 2:
Syntax Description
EGOFS(following axis,leading axis1,…,leading axis5)
This command parameter
setting made it possible to
selectively remove the influence
of the individual leading axes on
the following axis' motion.
At least one leading axis must be specified. The influence of the specified leading axes on
the slave is selectively inhibited. This call triggers a preprocessing stop. If the call still
includes active leading axes, then the slave continues to operate under their influence. If the
influence of all leading axes is excluded by this method, then the following axis is braked to a
standstill.
