FA1, FA2: Frequency arrival signals
Terminal function
A digital output configured as FA1 will be activated as soon as the set frequency has been reached. A digital
output configured as FA2 will stay activated at frequencies above those set under C 42 and C 43. In order to
provide for a certain amount of hysteresis during switching on and off, the FA1 and FA2 signals are activated
0.5Hz before the current frequency reaches the set value or the frequency set under C 42, respectively. The
FA1 and FA2 signals are then again deactivated 1.5Hz after the current frequency has passed the frequency
set under C 43.

1) If a programmable digital output is to be configured with FA2 output function, first of all a frequency
has to be set using C 42 at which the FA2 signal is to be activated during acceleration. Next a frequency
has to be set at which the FA2 signal is to be deactivated again, this is done using C 43.
2) Then configure under C 21 or C 22 one of the digital outputs 11 or 12 as FA1 or FA2 by entering the
parameter 01 for FA1 or 02 for FA2.
Remarks
• The transition of an FA1 or FA2 signal from the inactive to the active state is carried out with a delay of
approximately 60ms.
RUN: Motor running
Terminal function
A digital output configured as RUN stays activated as long as a frequency not equal to zero is sent to the
motor (i.e. as long as the motor is running in forward or reverse direction).
