PARAMETERS
 Details of the remote I/O signals
The device numbers described in this section are for the station number 1.
For the station number 2 and later, the device numbers are different. (Refer to the manual of the CC-Link master module for
the correspondence between device numbers and station numbers.)
● Output signals (Master module to converter (with the FR-A8NC))
Signals output from the master module (input to the converter) are as follows.
∗1 A signal shown is initially assigned to the terminal. Use Pr.3, Pr.4, or Pr.7 to assign a different input signal to the terminal. For the available
signals, refer to page 87 .
Note that the RES, OH, and LOH signals cannot be controlled through the network.
● Input signals (Converter (with the FR-A8NC) to master module)
Signals input to the master module (output from the converter) are as follows.
∗1
A signal shown is initially assigned to the terminal. Use Pr.11, Pr.12, or Pr.16 to assign a different output signal to the terminal. For the available
signals, refer to page 89 .
Device
number
Signal name Description
RY2
Converter stop
(Function of terminal SOF)
∗1
The function of a signal assigned to terminal SOF, RES, or LOH works.
RY5
Converter reset
(Function of terminal RES)
∗1
RY6
Box-type reactor overheat
protection
(Function of terminal LOH)
∗1
RYC Monitor command
When the Monitor command (RYC) signal turns ON, monitor values are set to the
remote register RWr0, 1, and 4 to 7, and the Monitoring (RXC) signal turns ON. While
the Monitor command (RYC) signal is ON, the monitor values keep being updated.
RYF Instruction code execution request
When the Instruction code execution request (RYF) signal turns ON, an action
corresponding to the instruction code set in RWw2 is executed. The instruction code
execution completion (RXF) signal turns ON after the instruction code execution is
completed. When an instruction code execution error occurs, a value other than "0" is
set in the reply code (RWr2).
RY1A Error reset request flag
When the Error reset request flag (RY1A) signal turns ON at a converter fault
occurrence, the converter is reset and the Error status flag (RX1A) signal turns OFF.
Device
number
Signal name Description
RX2 Inverter run enable OFF: The converter is not ready. ON: The converter is ready.
RX3
During converter reset
(Function of terminal RSO)
∗1
The function of a signal assigned to terminal RSO, RYA, or ABC works.
RX4
Inverter run enable
(Function of terminal RYA)
∗1
RX8 Fault (ABC signal)
∗1
RXC Monitoring
Turning ON the Monitor command (RYC) signal sets monitor values to the remote
registers RWr0, 1, and 4 to 7, and turns ON this signal. The Monitoring signal turns
OFF when the monitor command (RYC) signal turns OFF.
RXF
Instruction code execution
completed
Turning ON the Instruction code execution request (RYF) signal executes the
instruction code set in RWw2, and after the completion, this signal turns ON. This
signal turns OFF when the Instruction code execution request (RYF) signal turns OFF.
RX1A Error status flag
The signal turns ON at a converter fault occurrence (when the protective function is
activated). Output of the Error status flag signal depends on the retry function setting.
RX1B Remote station ready
This signal turns ON when the converter becomes ready after initial setting is
completed following a power-ON or a hardware reset.
The signal turns OFF at a converter fault occurrence (when the protective function is
activated).
The signal is used as an interlock during the write to/read from the master module.
