The speed is converted as shown below.
Master speed before

conversion
after conversion
The speed direction can be reversed and transmitted by setting a negative value in RatioNumerator.
The target velocity is changed if the gear ratio is changed during acceleration/deceleration. Therefore, the speed of Slave is
changed directly and the gear operation may be started depends on the change of the target velocity.

■RatioDenominator (Gear ratio denominator)
Set the denominator for converting the movement amount of Master and composing.
Set together with RatioNumerator.
Set a positive value in RatioDenominator.

■Acceleration (Acceleration)
Set the acceleration for accelerating.
When reaching the target velocity, InGear turns TRUE and Slave is controlled with the speed which converted the speed of
Master by the gear ratio.
