3.2.24 Master frequency input (DFIN)
Purpose
Converting and scaling a power pulse current at the digital frequency input X9 into a speed and phase
setpoint. The digital frequency is transferred in a high−precision mode (with offset and gain errors).

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