Running a Program
Chapter 7
7-13
Use the mid-start program feature to begin program execution from some
block other than the first block of the program. This is done without the
operator knowing what G, M, T, work coordinate offsets, etc. should be
active for that block’s execution or to re-execute all of the prior blocks to
establish these conditions.
When you perform a search with recall, the control finds a character string
or sequence number in a specific block for execution to begin from.
Execution always begins from the beginning of the block regardless of the
location in the block of the searched string or sequence number. This
searched block must be a block that would normally be executed during the
full programs execution (a block that would be skipped by some means
such as a jump, etc., cannot be searched for).
Important: If wheel radius compensation is activated it will require a
move to re-initialize. This can result in a different path than the program
path if the previous blocks had actually been executed. See page 15-17 or
15-27 for details on entry moves into compensation.
As the control proceeds through the program searching for the entered
character, it is setting active the necessary G, M, S, F, and T words. The
control also establishes the work coordinate system that should be active
for the execution of the selected block including all offsets and rotations to
the work coordinate systems.
You can also use the program search with recall feature to search into any
subprograms or paramacros that are contained in the main program. This is
provided of course, that the searched block is in the path of normal
program execution.
To perform a program search with recall, follow these steps:
