While the electronic gear function is being executed, the gear ratio can be
changed in real time from the G-language program.
It is possible to integrate other axes (i.e., other than the input axis and operat-
ing axis) with the axis that is being operated by the electronic gear. This
enables position compensation according to other axis positions.

Note: The input axis, operating axis, and integrated axis must all be different axes.
