10 Integrated Oscilloscope
10.1 Introduction
The iTNC 530 features an integrated oscilloscope
This oscilloscope has six channels, of which no more than four can be used for signals from the
current and speed controller. If more than four channels are to be displayed from the current and
speed controller, the error message Channel <number> cannot be displayed.
Advantages of the integrated oscilloscope for field service:
îš„ The actual values of physical quantities such as distance, velocity, acceleration can be
compared with the respective nominal values.
îš„ Observing the current I(nominal) and the signals derived from the current value, such as
I2-t (mot.), I2-t (p.m.), utilization permits conclusions about the tool in use, about
lubrication, the mechanics and the electrical drives.
îš„ The following error s diff and the signal Pos.Diff. are also significant for the mechanical
quality of a machine.
îš„ For analog axes s diff provides information on the speed adjustment at the servo amplifier.
îš„ By triggering to error markers it is possible to record the behavior of the machine shortly
before an error condition occurs.
îš„ Physical signals such as current, speed, etc. can be recorded together with
PLC signals.
îš„ Static and sliding friction at the quadrant transitions can be analyzed in a circular
interpolation test.
îš„ With the respective hardware and software version signals of encoders (position encoders,
motor encoders) can be recorded.
