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:

Switching-in the electronic gearbox (EGOFS, EGOFC)

There are 3 different ways to switch-out an active EG axis group.

EGOFS(following axis)

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
