Using the Function Block 10-5
Figure 10.2 shows how the input parameters for function input 1
work together. The input parameters for function inputs 2 and 3 work
in the same manner.
Figure 10.2
Input 1 Parameters for the Function Block
For example, if Function In1 (parameter 198) is 10001001.0001000,
Func 1 Mask/Val (parameter 199) is 10001101.0001001, and Func 1
Eval Sel (parameter 200) is set to 5 (any bit off), then a value of true is
passed to the function block. If Func 1 Eval Sel is set to 3 (all bits
off), then a value of false is passed to the function block. Figure 10.3
shows how this works.
Figure 10.3
Example of Function Input 1 Parameters
If you want to pass the value of Function In1 directly to the function
block without evaluating it, set Func 1 Eval Sel to 0.
Function In4 (parameter 207), Function In5 (parameter 208),
Function In6 (parameter 209), Function In7 (parameter 210), and
Function In8 (parameter 211) provide additional input values.
Using the Timer Delay Function You can use the function block to set up a timer delay. You can choose
how to evaluate the inputs and when you want to apply the timer by
using Function Sel.

The drive looks at only the bits
that are set in Func 1 Mask/Val if
modes 2, 3, 4, or 5 are selected
in Func 1 Eval Sel.
These two bits are different.
If parameter 200 = 5 (any bit off),
then result is True.
If parameter 200 = 3 (all bits off),
then the result is False.
