Overview

The TwinCAT 3 Bode Plot is the ideal tool for the analysis and optimization of mechanical resonances within a mechatronic system. The TwinCAT 3 Bode Plot can be used in conjunction with the AX5000 and AX8000 drive systems from Beckhoff. It shows the gain and the phase of a system for every frequency within a frequency range. A graphic display of the stationary reaction, at an output to a harmonic excitation (“sine oscillation”) at an input of a system, is thus possible with this tool within the scope of TwinCAT Measurement in Visual Studio. Problematic frequency ranges can easily be identified in the Bode Plot. With the help of Filter Sets, possible filter settings and their effects on the drive can be simulated in the TwinCAT Bode Plot before the settings for optimizing the drive axis are actually applied.

Key features:

• Representation of mechanical resonances
• Determination of the bandwidth, as well as phase and amplitude reserves
• Direct simulation of the filters and their effect on the system
• Adaptation of filters to optimize resonance points

Principle of operation:

For the harmonic excitation of a drive axis, the frequencies can be specified in the TwinCAT Bode Plot, integrated in Visual Studio as an independent Measurement project. The input data are transmitted in the real-time context and are then automatically followed for the selected axis. The current output values for amplitude gain and phase shift are continuously transmitted during the execution to the chart of the Bode Plot in order to graphically display the results.
