Description
With the PU connector, communication can be
made through RS-485.
The FR Configurator can be operated by con-
necting the inverter to the personnel computer
through USB.
Description
The alarm is output via relay contacts. The
block diagram shows the normal operation and
voltage free status. If the protective function is
activated, the relay picks up.

Switched low when the inverter output fre-
quency is equal to or higher than the starting
frequency (initial value 0.5Hz).
Switched high during stop or DC injection
brake operation.
The output is switched low once the output fre-
quency exceeds a value preset in Pr. 42 (or
43). Otherwise the FU output is switched high.
Reference potential for the signals RUN and
FU. This terminal is isolated from the reference
potential of the control circuit SD.
Select one e.g. output fre-
quency from monitor items.
The output signal is propor-
tional to the magnitude of
the corresponding monitor-
ing item.
Not output during inverter
reset.
