Description
1 changeover contact output indicates that the drive unit
protective function has activated and the output stopped.
Fault: discontinuity across B-C (continuity across AC),
Normal: continuity across B-C (discontinuity across A-C)
Switched low when the drive
unit rotation speed is equal to
or higher than the starting
rotation speed. 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 rotation speed and
high when less than the preset
detected rotation speed.
Common terminal of terminal RUN and FU.
Select one e.g. rotation speed from monitor items.
Not output during drive unit reset.
The output signal is proportional to the magnitude of the
corresponding monitoring item.
With the PU connector, communication can be made through RS-485.
Conforming standard: EIA-485 (RS-485)
Transmission format: Multidrop link
Communication speed: 4800 to 38400bps
Overall length: 500m
The USB connection with a personal computer can be established. Using FR
Configurator, setting, monitoring, and test operations of the drive unit can be
performed.
Interface: conforms to USB1.1
Transmission speed: 12Mbps
Connector: USB mini B connector (receptacle mini B type)
