6 Drive Programming Commands
For/Next
Command
Executes <command set> repeatedly until <vari-
able> started with <start value> reaches <end
value>. In every time of execution, <incremental
value> is added to <variable>. When the "next"
command is executed, a judgment with <end
value> is executed and <incremental value> is
added to <variable>.
 Example
Block number
1 to 4 Assigns 1 to U(01) and the value of U(01) to U(00). Waits for 1.00 second with the "wait" com-
mand. If U(01) is less than 8, 1 is added to U(01) and the next command after "for" is executed.
Goes to the next step after the "next" command if U(01) is equal to or greater than 8.
