Press "Program variable function."

Select "Conditional program branch."

Enter the "variable condition" (see figure to the top

right).

You can use both "Mathematical functions" and

"Calculating operations" in the same mathematical

expression. The mathematical functions are arranged

on two menu levels. To switch to the next menu level,

press ">>."

The "condition" includes a variable or mathematical

expression on either side of the relational operator

(see figure to the top right).

A "conditional branch" consists of the elements:

 "IF"—followed by a condition (comparison).

 "THEN"—if the condition is fulfilled, the THEN

branch is executed.

 "ELSE"—if the condition is not fulfilled, the ELSE

branch is executed.

 "ENDIF"—concludes the conditional program

branch.

After entering the "conditional program branch,"

program the NC blocks to be executed.

The "ELSE branch" can be omitted.
