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.)

Pr.289 = 9999

NOTE
• 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
invalid (no filter).

• 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.
• 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.
