Initial Value
This is the initial value of the user variable that will be used on power up. If the user variable
has been configured as a Save to NVM parameter, then the value in NVM will overwrite the
initial value on power up.
Adding and Deleting Variables
The default number of variables is ten. To add more user variables, click on the up arrow next
to the “Number of User Variables” window on the User Variables view. The maximum
number of user variables is 500.
Only the last variable in the list can be deleted. To delete the last variable, simple click on
the down arrow next to the “Number of User Variables” window.
User variables are all of a Global type, meaning that they can be accessed from any program.
Online Tab (not shown)
While online with the FM-3, an online tab will be shown on the lower half of the User
Variables view. This online tab will show the current value of each of the user variables.
Using Variables in a Program
Once setup, user variables can be used inside a program in calculations, motion profile setup,
or any other user-desired function. To access user variables, click on the Drag in Variables
icon in the user program toolbar. User Variables is a branch in the Drag In Variables selection
box.
