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 drive unit or analog circuit of output
devices.
· The drive unit will be damaged if power is applied to the drive unit output terminals (U, V, W). Never perform such
wiring.
· indicates that terminal functions can be selected using Pr.178 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 drive unit.
1 changeover contact output indicates that the drive unit 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 drive unit rotation speed is equal to or
higher than the starting speed (initial value 15r/min). Switched High
during stop or DC injection brake operation.
Switched Low when the drive unit rotation speed is equal to or
higher than the preset detected speed and High when less than the
preset detected speed.
Common terminal of terminal RUN and FU.
Used to output a selected monitored item (such as rotation speed)
among several monitored items. (Not output during drive unit
reset.) The output signal is proportional to the magnitude of the
corresponding monitoring item.
With the PU connector, RS-485 communication can be established.
· Conforming standard: EIA-485 (RS-485) · Transmission format: Multi-drop link
· Communication speed: 4800 to 38400bps · Overall extension: 500m
FR Configurator can be operated by connecting the drive unit to the personal computer through USB.
· Interface: conforms to USB1.1
· Connector: USB mini B connector (receptacle mini B type)
