The electronic gear is set by setting the travel value per pulse (see Section 4.2.1).
Using the electronic gear function allows positioning control without the need to
select the encoder to match the mechanical system.

(1) Electronic gear 1:1 (electronic gear setting = 1)
Travel value per pulse =
Positioning control is executed at the commanded speed.
(2) Electronic gear 2:1 (electronic gear setting = 0.5)
Travel value per pulse =
Positioning control is executed faster than the commanded speed.
(3) Electronic gear 1:2 (electronic gear setting = 2)
