4.5.1 Measuring the Signal Amplitudes with 11µApp Interface Board:
Definitions:
SYM.1:
Symmetry 1, ratio of positive to negative
half wave of incremental signal Ie1 (versus U
SYM.2:
Symmetry 2, ratio of positive to negative
half wave of incremental signal Ie2 (versus U
Calculation:
I1 / I2:
Amplitude ratio, amplitudes of incremental signals Ie1 versus Ie2
Calculation:
