Typical application
By means of this FB a traversing path within the limited traversing range can be simply changed via
factors. By this, the motion profile can be maintained.
[5-17] Example: spindle drive
• Thereby the factors always relate to the zero point of the motion profile on the y axis.
[5-18] Example: Decrease of the lift to 50 % with stretch factor = 0.5
