3.2.41 Digital frequency input (DFIN)
Purpose
Converting and scaling a pulsed current at the digital frequency input X9 into a speed and angle
setpoint. The digital frequency is transferred in a high−precision mode (without offset and gain errors).

Function
l The input X9 is designed for signals with TTL level.
l In the case of a digital frequency cascade or digital frequency bus, adapt the drive to the
connected encoder or upstream controller via C0425.
l The input of a zero track is optional.
l Via C0427 the following input signals can be evaluated:
C0427 = 0
