PA06 Set an electronic gear numerator.
CMX To enable the parameter, select "Electronic gear (0 _ _ _)" of "Electronic gear selection" in [Pr.
PA21].

numerator)
If the set value is outside this range, noise may be generated during acceleration/deceleration or
operation may not be performed at the preset speed and/or acceleration/deceleration time
constants.
Be sure to set the electronic gear with servo-off state to prevent unexpected operation due to
improper setting.
This parameter corresponds to "Motor revolutions (Index: 6091h, Sub: 1)". When this parameter is
mapped to the link device of CC-Link IE Field Network Basic, the value written with MR
Configurator2 is overwritten by the controller. Thus, do not write a value with MR Configurator2.
Setting range: 1 to 16777215
PA07 Set an electronic gear denominator.
CDV To enable the parameter, select "Electronic gear (0 _ _ _)" of "Electronic gear selection" in [Pr.
