Block display has no influence on reference machining.
3.7.2 Production Using Load Monitoring
If you wish to use the load monitoring function for
your machining processes, you must activate it in the
NC program (G996).
Display torque values and limit values:
”Display – Load monitoring – Display” (Automatic
operating mode).
”Load monitoring display” submenu:
■ ”Curves” menu item
Enter the required drives in the input fields ”Curves
1 to 4”.
■ Line graphics: One curve
■ Bar graphics: Up to four curves
Display grid: See § 3.7.1 Reference Machining”
■ ”Mode” menu group
■ Line graphic Display the torque values over the
time axis and limit values – limit values are gray:
nonmonitored area (rapid traverse paths are
hidden).
■ Bar graphic Displays current torque values,
previous ”work” and all limit values of the
monitoring zone
■ Bar graphic: Graphically display torque values
and mark the peak values
■ Save/do not save measured values
The measured values must be saved for later
analysis of reference machining. Check the setting
in the ”Save data” (”Write data”) display field.
■ Overwrite/Do not overwrite limit values
If you wish to retain the limit values after a new
reference machining cycle, select ”Do not
overwrite limit values.”
■ Pause stops the display
■ Continue continues the display
■ Auto: returns to the automatic menu
Additional information

Negative algebraic sign: Production is not
monitored (example: skipping the paths of rapid
traverse).
■ Tool: Active Tool.
