	Field/button	Explanation/instructions
Cyclic relative		If you select the cyclic relative execution type, the cam will be repeated
		starting at the end value of the slave axis. The first derivation of the cam
		(velocity) in the start and end point of the master range are identical.
		Possibly an identical value (average value) is forced from the target
		device.
		Note:
		If you activate Cyclic relative, the master range in the horizontal and
		vertical direction can be displayed repeatedly. You can optimize the
		display via the parameters Cycle start (slave) and Cycle length (slave).
	Cycle start (slave)(Cyclic relative	Under Cycle start (slave), enter the start point for the display in the
	activated)	vertical direction.
	Cycle length (slave)(Cyclic relative	Under Cycle length (slave), enter the length of the displayed range in the
	activated)	vertical direction.

Interpolation

Specify the interpolation for the target device here.

You can set the following parameters:

Table 4-5		Parameters in the Interpolation tab (Target Device Parameters window)
		Field/button	Explanation/instructions
Interpolation type			The curve in the master range can be made up of individual segments.
			Gaps may occur between the curve segments. If the gaps are greater
			than the maximum specified gap size, interpolation for the target device
			is performed between the end points of the curve segments.
			Under Interpolation type, specify the type of target device for which the
			interpolation is to be performed between the gaps.
	Linear		If you select the interpolation type Linear, there is a smooth closure of
			the gap through the insertion of a straight line segment between the
			interpolation points.
	Cubic splines		If you select the interpolation type Cubic splines, there is a smooth
			differentiable closure of the gap. The curve runs through the specified
			interpolation points.
	Bezier splines		If you select the interpolation type Bezier splines, the approximation
			curve runs along the specified interpolation points.
With gaps up to
	Master
		Leave gaps	Gaps may occur between the curve segments of the master axis. Here
			you can specify up to which size the gaps are maintained.
		Merge points	Gaps may occur between the curve segments of the master axis. Here
			you can specify up to which size the gaps are closed by merging the end
			points.
	Slave
		Leave gaps	Gaps may occur between the curve segments of the slave axis. Here
			you can specify up to which size the gaps are maintained.
		Merge points	Gaps may occur between the curve segments of the slave axis. Here
			you can specify up to which size the gaps are closed by merging the end
			points.
