SETUP ASSISTANCE
The set of utilities of the setup assistance is meant to speed up and simplify the
machine setup procedure. The setup assistance offers the following utilities.
• The oscilloscope.
• The circularity (roundness) test.
• The bode diagram.
It must be borne in mind that these utilities are assistance tools that only show the
system's response to the various adjustments; it is always up to the technician to
choose the best adjustment.
The oscilloscope
The oscilloscope is an assistance tool for adjusting the CNC and the drives. This utility
can graphically show 4 previously selected variables, modify their values and check
the different responses of the system.
Using the oscilloscope, it is possible to edit the CNC's machine parameters that affect
the adjustment; it is also possible to modify at the Sercos
®
drives the variables that
have writing permission. In any case, a protection password is required for modifying
the CNC's machine parameters or the drive's variables.
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.
