setpoint is activated by a PRBS signal. The evaluation of the signals is performed in the
frequency range.
● Current controller setpoint frequency response(after current setpoint filter)
For the reference frequency response on the current controller, the current setpoint is
activated by a PRBS signal. The evaluation of the signals is performed in the frequency
range.
