13.16.1.1 Configuration master frequency input signal
You configure the type of the master frequency input signal via C0427:
C0427 = 0 (2 phases)
Track CW rotation CCW rotation

Z
Z
A Track A leads by 90°
(DFIN_nIn_v = positive
value) Track A lags by 90°
(DFIN_nIn_v = negative
value)
B ˘ ˘
Signal sequence with phase shift (CW
rotation)
C0427 = 1 (A = speed / B = direction)
Track CW rotation CCW rotation
