Excitation Type
Excitation Type defines what type of signal will be used to excite the motor.
Three excitation types are available:
-
PRB: uses a pseudo random binary signal to excite the system. The signal is either + or – current or velocity amplitude (depending the injection point).
-
Sine: requires that the start frequency, end frequency, and frequency step size are specified. The sine sweep takes significantly longer than a noise or PRB measurement but is often cleaner. Be careful when selecting a step size: too large of a step size may miss important resonances, and too small of a step size increases measurement time.
-
Noise: uses a pseudo random noise signal to excite the system. The signal varies between +/- current or velocity amplitude (depending on injection point).
