Functional Description

The parameter represents the reference position that is generated by the reference position generator in units.

NOTE: In PacDrive systems, the user coordinate system is represented in units. Depending on the setting of the FeedConstant (units/revolution or units/m), the user coordinate system is mapped to the physical dimensions. In a multi carrier transport system, one user unit is mapped to 1 mm on the physical track. The setting of a FeedConstant is not supported.

Coordinate displacements with FC_SetposSingle() affect the parameter RefPosition.

NOTE: If EnableSet inside the user function CarrierState (see CarrierState) is disabled, the value of Position (see Position) is cyclically copied to RefPosition. If EnableSet is disabled while the carrier is still in motion, a jump occurs in RefPosition. The carrier does not react to this jump because it no longer follows the setpoint settings when EnableSet is disabled.
