numerator)
Set an electronic gear numerator.
To enable the parameter, select "Electronic gear (0 _ _ _)" of "Electronic gear selection" in [Pr.
PA21].
In the profile mode, cycle the power to enable the parameter.
The following shows a standard of the setting range of the electronic gear.

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.

Pt (servo motor resolution): 131072 pulses/rev
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

denominator)
Set an electronic gear denominator.
To enable the parameter, select "Electronic gear (0 _ _ _)" of "Electronic gear selection" in [Pr.
PA21].
In the profile mode, cycle the power to enable the parameter.
Setting range: 1 to 16777215

INP
In-position
range
Set an in-position range per command pulse.
To change it to the servo motor encoder pulse unit, set [Pr. PC24].
When [Pr. PC24] is set to "_ _ _ 0" in the profile mode, the unit can be changed 10
