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

Figure 6-58 Optimizing a controller
Depending on the form of controller optimization to be performed, it is possible to define the
quality (e.g. signal form, amplitude, transient recovery time) of the disabled signal, the
measuring duration for step functions in the time range, or the bandwidth and number of
averaging operations in the frequency range for the trace. The analytical and graphical
evaluation can then be performed accordingly (FFT diagram, Bode diagram).
