Oscilloscope
20.1.4 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
1 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.
2 At the oscilloscope, define the variables to be analyzed, the trigger conditions and the
machine parameters of the CNC or the drive that may be modified.
3 Data capture and later analysis of the data.
4 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.
5 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.
How to operate the oscilloscope.
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
[] [] 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
[] 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.
