In addition, Start/Jog Mask (parameter 126) should be set to
11111110.11111111.
Using the State Machine
Function
The state machine function lets you use a decision table to select
which value to use for the output based on the values of In2 and a
timer on In1. Figure 10.8 shows the state machine function block.

State Machine Function Block
As an example, you could use the state machine function block to set
up a speed profiler such as the one shown in Figure 10.9.
