PositionPositionProfile

The data type MC_PPROFILE is used for CamTable. An array has to be defined and provided at MC_CamTableSelect. Several CamTables could be defined and the axis could change between them on the fly. There is no routine of smooth movement from on table to the next so the user has to take care just to switch on appropriate positions.

MC_PProfile	Type	Comment
master_position	LREAL	Masterposition of interpolation point. Be careful, the values have to be in ascending order: MC_PProfile_Array [x].master_position < MC_Profile_Array [x+1].master_position.
interpolation_point	LREAL	Slaveposition of interpolation point.
Velocity_ratio	LREAL	Velocity value for interpolation point, is just relevant for MCA_POLY5 ans MCA_POLY3. It describes the relation of slave-velocity to master-velocity, e.g. velocity_ratio=1 “Master and Slave have the same velocity.
Acceleration_ratio	LREAL	Acceleration to be reached at this point. It is just relevant for MCA_POLY5. It gives the relation of slave-acceleration according to master acceleration.
