13.1.3 Configure and execute the oscilloscope function
In the oscilloscope mode, from a single screen, it is possible to select the variables
to be analyzed, the trigger conditions and the machine parameters of the CNC or the
drive that may be modified.
Operating procedure
Execute a part-program to move the axis or axes to be adjusted. Once the program
is running, go into the adjustment mode and access the oscilloscope function.
Define the variables to be analyzed, the trigger conditions and the machine
parameters of the CNC or the drive that may be modified.
Data capture and later analysis of the data.
Once the data capture has been interrupted or completed, it is possible to analyze
the signals and modify the parameters that have been previously selected in order
to improve the machining conditions.
Repeat the capture, the analysis and the modification of parameters until obtaining
the best machining conditions.
Recommendations
Execute endless repetitive movements. After adjusting the axes individually, readjust
the interpolating axes together.
The user must determine which is the best adjustment, the oscilloscope function is
just an assistance tool.
Operation
To enter or modify a data on the screens, it must be selected; in other words, it must
have the editing focus on it.
Use the [ ©] [ª] keys to select another editable data or field. It is a rotary selection,
if the [ ©] key pressed when the first element of the screen is selected, the focus goes
to the last element whereas if the [ ª] is pressed when the last element is selected,
the focus goes to the first element.
Not all the fields are editable, only the ones that may be selected can be edited, those
having the focus. There are two types of editable fields:
‡ Editable values:
They may be assigned a value, either a two-digit number or alphanumeric
(numbers and letters). Before validating the data, it is checked out and if it is not
correct, it will not be accepted and a warning message will be issued.
‡ Values that may be selected:
The possible data are fixed one of them must be selected. Use the [ ¨] [§] keys
to see the possible values. For this type of values that are icons, the [SPACE] key
has the same effect as the [
¨] key.
When capturing 1 or 2 variables of the same drive, the capture will be done
by the drive itself and the CNC will be in charge of drawing the results.
When capturing more than 2 variables or 2 variables from different drives, in
order to synchronize data, the capture will be done by the CNC and the
sampling period will be the CNC's cycle time.
