If the axis is moved with the system powered–down, then the saved stop posi-tion no longer matches the current position.As described under ”axis safely referenced” the ”axis safely referenced” state canalso be achieved using a saved and set user agreement and a saved stop position.The following conditions must be fulfilled: The saved user agreement must be available. The difference between the ”reference position” (power–on position with abso-lute measuring systems or reference position for incremental measuring sys-tems) and the saved stop position (including the traversing distance to the refer-ence point with ERN) must be within a tolerance window specified using theappropriate machine data.
