7.10.1 General information
The internal oscilloscope of the iTNC can operate at a maximum resolution of
only as fine as 600 µs, but the feedback control can operate at resolutions as
fine as 100 µs.
Frequencies higher than 1/(600 µs ⋅ 2) = 833 Hz result in undersampling. This
can result in misinterpretation of the oscilloscope image. High frequencies are
mirrored downward. For example, a 1000 Hz oscillation appears as a 833 Hz -
167 Hz = 666 Hz oscillation.
For the CC 61xx, the internal oscilloscope and TNCopt display effective values.
Linear motor setup
Note
In order to avoid misinterpreting the oscilloscope image, TNCopt should be
used when searching for oscillation frequencies or optimizing the
controller.
