Name Type Function
12-bit digital input FR-A5AX
z
Input interface used to set the inverter frequency accurately using external 3-digit BCD or
12-bit binary-coded digital signals.
z
Gains and offsets can also be adjusted.
Digital output
z
Among 26 standard output signals of the inverter, this option outputs any 7 selected
signals from open collector output terminals.
Extension analog
output
FR-A5AY
z
Outputs extra 16 signals which can be monitored on the FM and AM terminals such as
output frequency,
z
20mADC or 5V(10V)DC meter can be connected.
Relay output FR-A5AR
z
Among 26 standard output signals of the inverter, this option outputs any 3 selected
signals from relay contact output terminals.
Orientation, PLG
output (Note 3)
z
Used with a position detector (pulse encoder) installed on a machine tool spindle to stop
the spindle in position (orientation control).
z
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
be kept constant if load variation occurs.
z
The current spindle position and actual motor speed can be monitored on the operation
panel or parameter unit.
Pulse train input
FR-A5AP
z
A pulse train signal can be used to enter the speed command to the inverter.
Computer link
z
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
z
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
z
Operation/monitoring/parameter change of the inverter can be performed from a computer
or PLC.
Device Net
TM
FR-A5ND
z
Operation/monitoring/parameter change of the inverter can be performed from a computer
or PLC.
CC-Link (Note 2) FR-A5NC
z
Operation/monitoring/parameter change of the inverter can be performed from a PLC.
Communication
Modbus Plus FR-A5NM
z
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. CC-Link stands for Control & Communication Link.
3. The FR-A5AX (12-bit digital input) is required for orientation control.
