Details of setting items
■CombineMode (Addition/subtraction method selection)
Set the method to combine the movement amount of Master1 and Master2.
• 0: mcAddAxes
It adds the movement amount of Master1 and Master2 and outputs.
• 1: mcSubAxes
It subtracts the movement amount of Master2 from the movement amount of Master1 and outputs.
■GearRatioNumeratorM1 (Master axis 1 gear ratio numerator)
Set the value of numerator for when converting the movement amount of Master1 and combining.
The movement amount is converted as shown below.
Master1 movement amount
Master1 movement amount
=
after conversion before conversion
The movement amount can be reversed and combined by setting a negative value to GearRatioNumeratorM1.
■GearRatioDenominatorM1 (Master axis 1 gear ratio denominator)
Set the value of denominator for when converting the movement amount of Master1 and combining.
It is set with GearRatioNumeratorM1.
Set a positive value to GearRatioDenominatorM1.
■GearRatioNumeratorM2 (Master axis 2 gear ratio numerator)
Set the value of numerator for when converting the movement amount of Master2 and combining.
The movement amount is converted as shown below.
Master2 movement amount Master2 movement amount
=
after conversion
before conversion
The movement amount can be reversed and combined by setting a negative value to GearRatioNumeratorM2 (master axis 2
gear ratio numerator).
■GearRatioDenominatorM2 (Master axis 2 gear ratio denominator)
Set the value of denominator for when converting the movement amount of Master2 and combining.
It is set with GearRatioNumeratorM2.
Set a positive value to GearRatioDenominatorM2.
