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 following requirements must be met before starting a dry run:
The control must be prepared by the machine tool builder for
dry run. (The function is usually activated with a keylock switch
or a key)
The Program run submode must be activated
When dry run is activated, the spindle status and the spindle speed
are frozen.
NOTICE
Danger of collision!
In dry run mode, the control performs all movements (except
thread cuts) at rapid traverse. There is an increased danger of
collision during dry run mode!
Use the dry run mode only for air cuts
Reduce the feed rate with the override potentiometer if
necessary
After deactivation of dry run mode, the control returns to the
programmed feed rates and the programmed spindle speed.
