Details of setting items
■RatioNumerator (Gear ratio numerator)
Set the numerator value for converting the speed of Master and transmitting.
The speed is converted as shown below.
Master speed before
Master speed

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.
■MasterValueSource (Master axis data source selection)
Select the data souse of Master for transmitting the speed of Master. For details, refer to the following.
Page 427 Master Axis Data Source Selection
■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.
