should not be confused with the start angle of a data window.
Likewise, “END” is the graph end angle. This should not be confused
with the end angle of a data window. Note that the ending angle may
not always be exactly the value entered for this parameter but is
calculated by the tonnage monitor due to the way it handles the
waveform. “SCALE” is the percent of channel rating (or machine
rating when viewing the total) displayed on the y-axis. For instance, a
400 ton 4 channel machine will have a channel rating of 100 tons. If
the graph scale is set to 100%, the maximum tonnage value shown on
the graph will be 100 tons when viewing a channel, and 400 tons when
viewing the total. The reverse tonnage range is always ½ of the
forward range - so it would show -50 tons when viewing a channel and
-200 tons when viewing the total.
k) Number of Points - The tonnage monitor module indicates the number of sample points
taken during the last stroke in the upper right hand part of the screen.
This number will depend upon the speed of the press, size of the
working portion of the stroke, and the sample rate at which the module
is configured. The graph can not be displayed if less than 240 points
have been recorded. The maximum number of sample points is 4735
(4734 if sample rate is set at 200 microseconds). When the maximum
number is reached (such as hitting an overload or stopping the press in
the working portion of the stroke) no further samples are stored.
l) Increment Key - The text of this key changes depending on which parameter the editing
cursor (not the measuring cursor) is currently on. In all cases,
however, it will increment the value the editing cursor is on (assuming
the operator has access via RUN/PROG key or access code). Note that
an operator can effectively “drag” limits and data window angles on
the graph by holding this key down.
m) Decrement Key - The text of this key changes depending on which parameter the editing
cursor (not the measuring cursor) is currently on. In all cases,
however, it will decrement the value the editing cursor is on (assuming
the operator has access via RUN/PROG key or access code). Note that
an operator can effectively “drag” limits and data window angles on
the graph by holding this key down.
