4 ADVANCED POSITIONING CONTROL
4.3 Setting the Block Start Data
Restrictions when the NEXT start is used
NEXT start instruction shows the end of the repetition when the repeated start (FOR loop) and repeated start (FOR condition)
are executed. (
Page 164 Repeated start (FOR loop),
Page 165 Repeated start (FOR condition))
This section describes the restrictions when 6: NEXT start is set in Block start data.
• The processing when 6: NEXT start is executed before the execution of 4: FOR loop or 5: FOR condition is the same as
that for 0: Block start.
• The repeated processing will not be performed if 6: NEXT start is not set after 4: FOR loop or 5: FOR condition. (Note that
no error occurs in this case.)
• Nesting is not possible between 4: FOR loop and 6: NEXT start, or between 5: FOR condition and 6: NEXT start. If nesting
is attempted, FOR to NEXT nest construction (Warning code: 09F1H) occurs. The destination of jump by NEXT at the 7th
point is changed to the 4th point and NEXT at the 9th point is processed as Normal start.
When a nest construction is not configured
When a nest construction is configured
A warning occurs when FOR at the 4th point is executed.
The destination of jump by NEXT at the 7th point is changed to the 4th point
and NEXT at the 9th point is processed as Normal start.
