On while the inverter is running. (Note)
Switched on when the output frequency reaches the set frequency ± Pr. 41.
Switched on when stall prevention is activated and switched off when stall prevention is
deactivated.
Reserved for the system.
Switched on when the output frequency reaches set frequency. (Note)
Switched on when the inverter's protective function is activated to stop the output. (Note)
Reserved for the system.
Switched on when the monitored value is set to RWr
switching on. Switched off when the monitor command (RYC) is switched off.
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.
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.
Switched on on completion of the processing corresponding to the instruction code
(RW
) which is executed when the instruction code execution request (RYF) switches
W2
on. Switched off when the instruction code execution completion (RXF) is switched off.
