Note: 1. Three plug-in 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. The FR-A5AX (12-bit digital input) is required separately to input the stop position command
externally for orientation control.

Type
Input interface used to set the inverter frequency accurately using external 3-digit BCD or
FR-A5AX 12-bit binary-coded digital signals.
Gains and offsets can also be adjusted.
Outputs any seven selected signals from among the inverter output signals from open
collector output terminals.
FR-A5AY
Outputs signals which can be monitored on the FM and AM terminals such as output
frequency, output voltage and output current.
20mADC or 5V(10V)DC meter can be connected.
This option outputs any three signals from among the inverter output signals from relay
FR-A5AR
contact output terminals.
Used with a position detector (pulse encoder) installed on a machine tool spindle to stop
the spindle in position (orientation control).
The motor speed is detected by the pulse encoder and this detection signal is fed back to
the inverter to automatically compensate for speed variation. Hence, the motor speed can
FR-A5AP
be kept constant if load variation occurs.
The current spindle position and actual motor speed can be monitored on the operation
panel or parameter unit.
A pulse train signal can be used to enter the speed command to the inverter.
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.
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.
FR-A5NP
FR-A5NPA
Operation/monitoring/parameter change of the inverter can be performed from a computer
or PLC.
FR-A5ND
FR-A5NC Operation/monitoring/parameter change of the inverter can be performed from a PLC.
Operation/monitoring/parameter change of the inverter can be performed from a computer
FR-A5NM
or PLC.
