Rate

Specifies how fast each segment runs. The following methods are supported:

Frequency, Time, Rate

Frequency specifies the time to run a two-segment cycle.

Rate specifies a constant rate between the starting level and the end
levels.

Note:

You cannot use Rate for a command activity that applies to multiple

rate between each end level is a constant linear rate (as with ramp shape)
or a varying rate (as with sine shape). The choices are:

Click the toggle button to select one of the wave shape choices or a variable.

Specify the number of end levels. Click the toggle button to specify a numeric
value and unit of measure or variable.

Number of Cycles

When using the numeric mode, the resulting number of end levels can be
specified by the number of Segments or by the number of Cycles. A segment
has one end level and a cycle has two end levels.
