13.2 The Bode diagram
The Bode diagram is an assistance tool for adjusting the CNC and the drives. This
utility may be used to obtain the Bode diagram of the response amplitude depending
on the frequency of the input signal.
With this tool, it is possible to insert a sinusoidal signal into an axis, so that changing
the frequency and analyzing the response provides the behavior of the axes at
different frequencies and will give the user an idea of how it behaves with any signal.
This diagram may be used to check the system's gain, the bandwidth and the
mechanical resonance. All this helps achieve the proper adjustment of the loops,
analyze mechanical problems and check the final features.
The Bode diagram is an assistance tool that only shows the response of the system
to the various settings (adjustments); it is up to the technician to choose the best
adjustment.
How to access the Bode diagram
The Bode diagram may be accessed from the softkey menu for setup assistance.
