2.4.3 Program execution with dry run feedrate
Functionality
The part program can be started via interface signal:
DB21, ... DBX7.1 (NC Start).
If this function is activated, the traversing speeds programmed in conjunction with G01, G02,
G03, G33, G34, and G35 are replaced by the feedrate value stored in setting:
SD42100 $SC_DRY_RUN_FEED.
The dry run feedrate value also replaces the programmed revolutional feedrate in program
blocks with G95.
Use
Danger
Workpieces may not be machined when "dry run feedrate" is active because the altered
feedrates might cause the permissible tool cutting rates to be exceeded and the workpiece
or machine tool could be damaged.
Selection
Dry run feedrate mode is selected via the operator interface in the "Program control" menu.
This selection sets interface signal:
DB21, ...DBX24.6 (Dry run feedrate selected).
This does not activate the function. In addition, the required dry run feedrate value must be
entered in the "Setting data/JOG data" menu.
Activation
The function is activated via interface signal:
DB21, ... DBX0.6 (activate dry run feed)
