1 changeover contact output indicates that the inverter
protective function has activated and the output stopped.
Fault: discontinuity across B-C (continuity across A-C),
Normal: continuity across B-C (discontinuity across A-C)
Switched low when the inverter output frequency is equal to
or higher than the starting frequency (initial value 0.5Hz).
Switched high during stop or DC injection brake operation.*
Switched low when the inverter output frequency is equal to
or higher than the preset detected frequency and high when
less than the preset detected frequency.*
Common terminal of terminal RUN and FU.
Select one e.g. output
frequency from monitor items.
Not output during inverter
reset. Not output during
inverter reset.
The output signal is
proportional to the magnitude
of the corresponding
monitoring item.
Terminal Name
