Note
Set Pr. 267 and a voltage/current input switch correctly, then input an analog signal in accordance with the setting.
Applying a voltage with voltage/current input switch in "I" position (current input is selected) or a current with switch
in "V" position (voltage input is selected) could cause component damage of the inverter or analog circuit of output
devices.
The inverter will be damaged if power is applied to the inverter output terminals (U, V, W). Never perform such wiring.
indicates that terminal functions can be selected using Pr. 178 to Pr. 184 and Pr. 190 to Pr. 192 (I/O terminal function
selection).
Terminal names and terminal functions are those of the factory set.
When connecting the DC power supply, be sure to connect the plus side of the power supply to terminal P/+ and
minus side to terminal N/-. Opposite polarity will damage the inverter.

1 changeover contact output indicates that the inverter fault occurs.
Fault: discontinuity across B-C (continuity across A-C), Normal: continuity across B-C
(discontinuity across A-C) Contact capacity 230VAC 0.3A (power factor = 0.4) 30VDC 0.3A
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.
Used to output a selected monitored item (such as Output
frequency) among several monitored items. (Not output during

inverter reset.) The output signal is proportional to the
magnitude of the corresponding monitoring item.
With the PU connector, RS-485 communication can be established.
