MC_CombineAxes, MCP_CombineAxes – Combine the motion of 2 axes into a third axis

Block SymbolsLicensing group: MOTION CONTROL
PIC PIC

Function Description

The MC_CombineAxes block combines a motion of two master axes into a slave axis command. The slave axis indicates synchronized motion state. Following relationship holds:

SlavePosition = Master1Position GearRatioNumeratorM1 GearRatioDenominatorM1 + +Master2Position GearRatioNumeratorM2 GearRatioDenominatorM2

Negative number can be set in GearRatio... parameter to obtain the resulting slave movement in form of difference of master axes positions.
