Switching-In The Electronic Gearbox (Egofs, Egofc) - Siemens Sinumerik 840D sl Programming Manual

Response of the Electronic gear at Power ON, RESET, mode change, block search
• No coupling is active after POWER ON.
• The status of active couplings is not affected by RESET or operating mode switchover.
• During block searches, commands for switching, deleting and defining the electronic gear
are not executed or collected, but skipped.
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_ ...

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
EGOFS(following axis)
Version 2:
Syntax
EGOFS(following axis,leading
axis1,...,leading axis5)
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.

Description
The electronic gear is deactivated. The following axis is
braked to a standstill. This call triggers a preprocessing stop.
Axis couplings
9.4 Electronic gear (EG)
Description
This command parameter
setting made it possible to
selectively remove the influence
of the individual leading axes on
the following axis' motion.
