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.

Switched Low when the inverter output frequency is equal to or
Inverter running 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.
