AC890PX AC Drive
Modifying a Block Diagram

Using the keypad you can modify the parameter values within a function block.

Using the DSE Configuration Tool, you can modify the parameter values within a function block, and
also make and break links within the shipping configuration. The Help in the DSE Configuration Tool
explains this process.
Programming Rules
The following rules apply when programming:

Function block output parameter values cannot be changed (because they are a result of the
function block’s processing)

Function block input parameter values that receive their values from an internal link in the Block
Diagram cannot be changed (as they will change back to the value they receive from the link
when the Drive is running).
Saving Your Modifications
If parameter values have been modified, the new settings must be saved. The Drive will then retain the new
settings during power-down. Refer to Chapter 9: “The Keypad” - Saving Your Application.
