Selection/activation
The selection signal normally comes from a user machine control panel.
This function must be activated by the PLC user program via the IS "Activate single block"
(V3200 0000.4).
The preselection whether "Single block coarse" or "Single block fine" type is made in the
user interface in the "Program control" menu.
Display
The checkback signal that single block mode is active is displayed in the relevant "SBL" field
on the operator interface.
Because of the single block mode, as soon as the part program processing has processed a
part program block:
● The following interface signals are set:
– IS "Channel status interrupted" (V3300 0003.6)
– IS "Program status stopped" (V3300 0003.2)
● The following interface signals are reset:
– IS "Channel status active" (V3300 0003.5)
– IS "Program status running" (V3300 0003.0)
10.4.4 Program processing with dry run feedrate (DRY)
Functionality
The part program can be started via IS "NC Start" (V3200 0007.1). When the function is
active, the traversing velocities programmed in conjunction with G1, G2, G3, CIP, and CT
are replaced by the feed value stored in SD42100 DRY_RUN_FEED. The dry run feedrate
also replaces the programmed revolutional feedrate in program blocks with G95. However, if
the programmed feedrate is larger than the dry run feedrate, then the larger value is used.
CAUTION
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.
