numerator) Set the numerator of the electronic gear.
To enable the parameter, set "Electronic gear selection" to "Electronic gear (0 _ _
_)", "J3 electronic gear setting value compatibility mode (2 _ _ _)", or "J2S electronic
gear setting value compatibility mode (3 _ _ _)" in [Pr. PA21]. For MR-J4-03A6 servo
amplifiers, "J3 electronic gear setting value compatibility mode (2 _ _ _)" and "J2S
electronic gear setting value compatibility mode (3 _ _ _)" cannot be selected.
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.

Note. This parameter is supported with software version B4 or later.
Always set the electronic gear with servo-off state to prevent unexpected operation
due to improper setting.

denominator) Set the denominator of the electronic gear.
To enable the parameter, set "Electronic gear selection" to "Electronic gear (0 _ _
