Inboard options
Name Type Function
12-bit digital input FR-A5AX
Input interface used to set the inverter frequency accurately using external 3-digit BCD or
12-bit binary-coded digital signals.
Gains and offsets can also be adjusted.
Digital output
Among standard output signals of the inverter, this option outputs any 7 selected signals
from open collector output terminals.
Extension analog
output
FR-A5AY
Outputs extra 16 signals which can be monitored on the FM and AM terminals such as
output frequency, output voltage and output current, etc.
20mADC or 5V(10V)DC meter can be connected.
Relay output FR-A5AR
Among 26 standard output signals of the inverter, this option outputs any 3 selected
signals from relay contact output terminals.
Auxiliary Control
(Note2)
FR-A5AC
Eight 120VAC inputs which implement the input terminal functions of the inverter.
Two relay outputs which are selected from among standard outputs.
Analog input-output
function
(Note2)
FR-A5AN
One isolated 4-20mA input which can set the frequency command to the inverter.
Two Isolated 4-20mA outputs which can be connected to an analog meter or other
compatible device.
Computer link
Operation/monitoring/parameter change of the inverter can be performed under the control
of a user program from a computer, e.g. personal computer or FA controller, connected by
a communication cable.
Relay output
FR-A5NR
Any one output signal can be selected from among the standard output signals of the
inverter and output as a relay contact (contactor) signal.
Profibus DP FR-A5NP
Operation/monitoring/parameter change of the inverter can be performed from a computer
or PLC.
DeviceNet
TM
FR-A5ND
Operation/monitoring/parameter change of the inverter can be performed from a computer
or PLC.
CC-Link (Note 3) FR-A5NC
Operation/monitoring/parameter change of the inverter can be performed from a PLC.
Communication
Modbus Plus FR-A5NM
Operation/monitoring/parameter change of the inverter can be performed from a computer
or PLC.
Note: 1. Three inboard options may be mounted at the same time (the number of the same options mountable is only one, and only one
of the communication options may be mounted.)
2. NA version only.
3. CC-Link stands for Control & Communication Link.
