MLPrfWriteIScale

 Function A function calculates a result according to the current value of its inputs. A function has no internal data and is not linked to declared instances. - Sets the Input Ratio value of a selected CAM Profile The position of a slave axis is mathematically linked to the position of a master axis. Example: A system where two rotating drums turn at a given ratio to each other. A more advanced case of electronic gearing is electronic camming. With electronic camming, a slave axis follows a profile that is a function of the master position. This profile need not be linear but it must be a mathematical function..

Inputs

Input	Data Type	Range	Unit	Default	Description
ProfileID	DINT	-2147483648 to 2147483647	N/A	No default	ID number of an initialized CAM Profile.
Ratio	LREAL	Positive Position means a point in space which is described by different coordinates. Depending on the used system and transformation it can consist of a maximum of six dimensions (coordinates).This means three Cartesian coordinates in space and coordinates for the orientation. In ACS there can be even more than six coordinates. If the same position is described in different coordinate systems the values of the coordinates are different.	N/A	No default	Desired new value of Input Ratio.

Outputs

Output	Data Type	Range	Unit	Description
Default (.Q)	BOOL			Returns TRUE if the Input Ratio is changed to the new value. See Pipe Network - General Rules.

Remarks

• Previous function name: MLPrfSetIRatio
• Ratios can be changed on the fly to modify the CAM Profile while maintaining its basic shape.
• A change in input ratio is equivalent to stretching the CAM Profile on the X (or Input) Axis.
