OFF : Other than forward running (during stop or reverse rotation)
ON : Forward running
RX1 Reverse running
OFF : Other than reverse running (during stop or forward rotation)
ON : Reverse running
RX2 Running (RUN) On while the inverter is running. (Note)

±
Pr. 41.
RX4 Overload (OL)
Switched on when stall prevention is activated and switched off when stall prevention is
deactivated.
RX5 Reserved Reserved for the system.
RX6 Frequency detection (FU) Switched on when the output frequency reaches set frequency. (Note)

Reserved Reserved for the system.
RXC Monitoring
Switched on when the monitored value is set to RWr
0
by the monitor command (RYC)
switching on. Switched off when the monitor command (RYC) is switched off.
RXD
Frequency setting command
(RAM)
Switched on when the set frequency is written to the inverter by the frequency setting
command (RYD) switching on. Switched off when the frequency setting command
(RYD) is switched off.
RXE
Frequency setting command
(E
2
PROM)
Switched on when the set frequency is written to the inverter by the frequency setting
command (RYE) switching on. Switched off when the frequency setting command
(RYE) is switched off.
RXF
Instruction code execution
completion
Switched on on completion of the processing corresponding to the instruction code
(RW
W2
) which is executed when the instruction code execution request (RYF) switches
on. Switched off when the instruction code execution completion (RXF) is switched off.
