Running a Program
Chapter 7

You can use the
<FEEDRATE OVERRIDE>
to modify the cutting feedrate.
Your system installer determines in AMP if rapid feedrates are overrides
by the
<RAPID FEEDRATE OVERRIDE>
switch/button or the
<FEEDRATE
OVERRIDE>
switch during Dry Run.
CAUTION: When testing a program using Dry Run, the
control still recognizes and executes M-, B-, S-, and T-codes.
To ignore M-, B-, S-, and T-codes, execute Dry Run in
conjunction with miscellaneous function lock. See section
8.1.2.
WARNING: Your system installer can write PAL to allow the
operator to select DRY RUN at any time. This means that
during normal automatic operation, the operator can select
maximum cutting feedrate and replace all feedrates
programmed with an F-word with the AMP assigned DRY RUN
feedrate. This can result in damage to the machine, part, or
injury to the operator.
