Parameters (M) Monitor display and monitor output signal
FR-A800 5 - 367
Adjusting the output terminal response level (Pr. 289)
The response level of the output terminals can be delayed in a range of 5 to 50 ms. (Operation example
for the RUN signal.)
Inverter operation ready signals (RY, RY2 signals)
and inverter running signals (RUN, RUN2, RUN3 signals)
●
Operation under V/F control and Advanced magnetic flux vector control
– When the inverter is ready for operation, the Inverter operation ready (RY) signal turns ON
(stays ON during operation.)
– When the inverter output frequency reaches Pr. 13 "Starting frequency" or higher, the Inverter
running (RUN, RUN2) signals turn ON. The signal is OFF while the inverter is stopped and during
DC injection brake operation. Inverter
– The Inverter running and start command is ON (RUN3) signal is ON while the inverter is running
or the start signal is ON. (When the start command is ON, the RUN3 signal output turns ON
even while the inverter's protective function is activated or the MRS is ON.) During DC injection
brake operation as well, the output is ON, and when the inverter stops, it turns OFF.

NOTES When Pr. 157 "OL signal output timer" is set for the Overload warning (OL) signal output, the OL
signal is output when the set time of (Pr. 157 + Pr. 289) elapses.
For the output signal and the fault code output (on page 5-382) used in the PLC function (on page
5-587), the Pr. 289 setting is invalid (no filter).
