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.

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.)

PROM write selection (when used with the FR-A5NR or FR-A5NC)
Pr.342 "E
2
PROM write selection" is valid for computer link operation with an option (FR-A5NR) or CC-Link
communication operation with an option (FR-A5NC).

Parameters are written to RAM when parameter write is
performed from the master.
When write to RAM is set, new parameter settings are cleared at power-off of the inverter. Therefore, when
the inverter is powered on again, the parameter settings are the values stored into E
2
PROM previously.
Note: When changing the parameter values frequently, set "1" in Pr. 342 to write them to RAM.
Performing frequent parameter write with "E
2
PROM write" set will shorten the life of the E
2
PROM.
