Chapter 10
Using the Function Block
Chapter Objectives Chapter 10 provides information for helping you to use the function
block that is included with the 1336 IMPACT drive.
What is a Function Block? A function block is a group of parameters that work together to add
flexibility to the 1336 IMPACT drive. The function block that is
provided with the 1336 IMPACT drive lets you set up a timer delay,
state machine, multiply/divide, add/subtract, scale, an up/down
counter, or a maximum/minimum function by using a combination of
17 parameters. Because these functions use the same parameters, you
can only use one of the function blocks (such as the timer delay) in
your application.
Figure 10.1 provides an overview of the function block.
