numerator)
Set the numerator of the electronic gear.
To enable the parameter, set "Electronic gear selection" to "Electronic gear (0 _ _ _)"
or "J3A electronic gear setting value compatibility mode (2 _ _ _)" in [Pr. PA21].
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.

Always set the electronic gear with servo-off state to prevent unexpected operation
due to improper setting.
