performed with a large value set as the in-position range.

(4) Electronic gear switching
The combination of CM1 and CM2 gives you a choice of four different electronic gear numerators set in
the parameters.
As soon as CM1/CM2 is turned ON or OFF, the molecule of the electronic gear changes. Therefore, if
any shock occurs at this change, use position smoothing (parameter No. 7) to relieve shock.
