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).
The following measuring functions are available:
● Setpoint jump at current controller
● Reference frequency response at current controller
● Setpoint jump at speed controller
● Disturbance variable jump at speed controller
● Reference frequency response at speed controller
● Disturbance frequency response at speed controller
● Speed-controlled system (input at current setpoint filter)
