Execution of a part program continues until the control encounters an M02
or M30. If the control does not encounter an M02 or M30 at the end of a
program, the error message “MISSING M02/M30” appears.
You can stop execution at any time by using any of the methods described
on page 7-2 or by pressing the
button.
Use the program recover feature to resume a program that was executing
and was interrupted by some means such as a control reset, E-Stop, or even
power failure in some cases.
This feature enables the control to return to the block in the program that
execution was interrupted at. This is done without the need for the
operator to remember the block that was interrupted or the need to
re-execute all of the prior blocks to reestablish modal operating conditions.
When you preform a program recover, the control automatically returns the
program to the beginning of the block that was interrupted. In the case of
power fail, the control even reselects the program as active.
