Function
The "electronic gear" function allows you to move a drive axis as a
following axis in synchronism with up to five leading axes. The
electronic gear is encoded via the following axis and has several lead
axes, each of which applies a gear ratio. The ratio to the drive axis
has a linear response and is defined as a coupling factor, numerator
to denominator. A gear group is defined and activated during part
program execution.

gear stages. The motion component of the following axis is derived
from the coupling factors of the individual leading axes.
