Relay output
(alarm output)
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.

RUN Inverter running
Switched low when the inverter output fre-
quency is equal to or higher than the starting fre-
quency (initial value 0.5 Hz).
Switched high during stop or DC injection brake
operation.
Permissible
load:
24 V DC (max.
27 V DC), 0.1 A
(A voltage drop
is 3.4 V maxi-
mum when the
signal is on.)
FU
Frequency
detection
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.
SE
Open collector

Reference potential for the signals RUN and FU.
This terminal is isolated from the reference poten-
tial of the control circuit SD.
