am Run Mode
Program execution in “dry run” mode
The dry run mode is used for fast program execution up to a point at
which machining is to resume. The prerequisites for a dry run are:
„ The MANUALplus must be prepared by the machine tool builder for
dry run (The function is activated with a keylock switch or a key.)
„ The Program Run mode must be activated
In dry run, all feed paths (except thread cuts) are traversed at the rapid
rate. You can reduce the traversing speed with the feed rate override.
Do not use the dry run feature for anything other than “cutting air.”
When dry run is activated, the spindle status or spindle speed is
“frozen.” After deactivation of the dry run, the MANUALplus returns
to the programmed feed rates and spindle speeds.
Use the dry run feature only to “cut air.”
