Measuring functions, trace, and function generator

Drive optimization
Drive optimization is part of commissioning and can be performed with SIMOTION SCOUT.
Controller optimization may only be performed by skilled personnel with knowledge of
control engineering.
Controller optimization
Various measuring functions are available for drive controller optimization. Using simple
parameterization, these measuring functions enable the influence of higher-level control
loops to be selectively switched off and the dynamic response of individual drives to be
analyzed. The function generator and trace recorder are used.
The control loop is supplied with the function generator signal at a specific point (e.g. speed
setpoint), and the signal is recorded by the trace recorder at another point (e.g. speed actual
value).

Depending on the form of controller optimization to be performed, it is possible to define the
quality (e.g. waveform, amplitude, settling time) of the disabled signal, the measurement
period for jump functions in the time range, or the bandwidth and number of averaging
operations in the frequency range for the recording. The analytical and graphical evaluation
can then be performed accordingly (FFT diagram, Bode diagram).
