3.5.3 Deleting Dies
To delete a die, select it the list Figure 3.9 and
hit the “Delete Die” button. A message box will
appear to verify that the die is to be deleted. Hit the
“Yes” button to delete the die or the “No” button to
abort the deletion.
3.6 Configuring Tonnage Wave Capture
LinkNet has tonnage signature capture built in.
In fact, the system can be set up so that tonnage
monitor equipped presses can print a waveform right
from the press. To do this, LinkNet needs to know
the orientation (portrait or landscape) of the paper
and the printer to use. Select “Tonnage Wave
Capture” from the “Configure” menu as shown in
figure 3.1 to bring up the dialog box of figure 3.12.
Figure 3.12: Tonnage Waveform Capture Config
This dialog box allows contains the settings for
two different print types. Reference printouts print
out each channel of the tonnage monitor separately
(but still on one page) as well as numerical peak
tonnage and setpoint information. View printouts
print whatever is viewed on the screen as large as
possible on the printer. For each printer, choose the
default paper orientation and the printer to use.
Note that these settings can be changed when
the graph is printed from LinkNet, but if the graph is
printed directly from a press, it will automatically
use the Reference Graph settings.
In addition to the printer settings, there are two
parameters called “Auto-Scale X Percent” and
“Auto-Scale Y Percent”. These parameters control
the amount of space LinkNet will try to leave around
a tonnage signature graph when it automatically
scales the graph when a new signature is captured.
The typical values of 10% for X and 5% for Y
should work in most applications.
3.7 Configuring Preventive Maintenance
Preventive maintenance (PM) allows one or
more setpoints to be entered for each machine or
die. These setpoints can be set by elapsed time,
press running time, and strokes. OmniLink 5000
controls additionally support setpoints by “Motor
On” time, Total feed length, and Clutch/Brake
Note that even if a job has been stored, settings
associated with the Press Control, Die
Protection, Tonnage Monitor, Programmable
Limit Switch, Auto-Setup Board, Speed
Control, and other specific press related
settings which can affect machine/tool
protection and/or operator safety can only be
modified at the machine. This allows setup
personnel to test and verify the configuration at
the machine where they can see what effect
changes have on the production process. A
simple illustration of possible problems with
modifying a job at the computer instead of the
press would be a mis-typed shutheight value. If
too low, the press or die could catastrophically
malfunction and/or break and possibly injure
people in the area as well as cause equipment
damage.
