Reference
Table 28: DO UNTIL
DO UNTIL Do/Until Statement
Purpose The DO / UNTIL statement is used to execute a statement or set of statements repeatedly until a
logical condition becomes true. The Do / Until statements enclose the program code to be repeatedly
executed with the UNTIL statement containing the logical statement for exit of the loop.
Syntax DO
{statement(s)}…
UNTIL <condition>
{statement(s)} any valid statement(s)
<condition> The condition to be tested.
Remarks The loop statement or statements contained within a DO / UNTIL loop will always be executed at least
once because the logical condition to be tested is contained within the UNTIL statement in the last
statement of the loop.
See Also WHILE, IF
Example:
V0 = 0 ; Set V0 to Value 0
; Create Loop to perform Move command 12 times
DO ; Start of Do Loop
V0 = V0 + 1 ; Add 1 to Variable V0
Moved 5 ; Move (incremental) distance 5
Until V0 == 12 ; Loop back to DO Statement, Repeat Until Logic True

Purpose Enable turns on power to the motor. Drive shows ‘Run’ on display when in the enabled state.
