RXnB Reserved* Reserved*
RXnC Monitoring flag
Switched on when the monitored values are set to RWrn,
RWrn+1, RWrn+4 to RWrn+7 by the monitor command
(RYnC) switching on. Switched off when the monitor
command (RYnC) is switched off.
RXnD
Frequency setting completion flag
(RAM)
Switched on when the set frequency is written to the inverter
by the frequency setting command (RYnD) switching on.
Switched off when the frequency setting command (RYnD)
is switched off.
RXnE Reserved* Reserved*
RXnF
Instruction code execution
completion flag
Switched on completion of the processing corresponding to
the instruction code (RWw+2) which is executed when the
instruction code execution request (RYnF) switches on.
Switched off when the instruction code execution completion
flag (RXnF) is switched off.
RX(n+1)0
to RX(n+1)9
Reserved* Reserved*
RX(n+1)A Error status flag
Switched on when occurred an inverter error or option error
(watchdog error, CPU error, ROM error or RAM error).
It is not switched on besides that.
RX(n+1)B Remote station ready
Switched on when the inverter goes into the ready status on
completion of initial setting after power-on or hardware reset.
(Used as an interlock for read/write from/to the master.)
Switched off when an inverter error occurs (protective
function is activated).
RX(n+1)C
to RX(n+1)F
Reserved* Reserved*
"n" is depend on the station number.
