Zero Positions
The default zero position is the initial placement position of a motion axis component reference relative to an assembly reference. To use a different position as the zero position, move the position of the component and click Set Zero Position. This new zero position is now the reference for the current position offset, the regeneration value, and maximum, and minimum limits of component movement. To use the default zero position as the zero position reference, click Default Zero Position.
The offset of the zero position from the default zero position is called the zero position offset. This is a motion axis parameter and can be used in relations and Family Tables.
