NOTE
• When Pr.157 OL signal output timer is set for the Overload warning (OL) signal output, the OL signal is output after the time
period calculated by adding the Pr.289 setting to the Pr.157 setting elapsed.
• The signal output for the PLC function (see
by the Pr.289 setting (not filtered for responsivity).
 Inverter operation ready signals (RY signal) and inverter running signals
(RUN, RUN2, RUN3 signals)
• When the inverter is ready for operation, the Inverter operation ready (RY) signal turns ON (and stays ON during
operation).
• When the inverter output frequency reaches the setting of Pr.13 Starting frequency or higher, the inverter running signals
(RUN, RUN2 signals) turn ON. The signals are OFF while the inverter is stopped or during the DC injection brake operation.
• The Inverter running and start command ON (RUN3) signal is ON while the inverter is running or while the start command
signal is ON (When the start command signal is ON, the RUN3 signal is ON even while the inverter's protective function
is activated or while the MRS signal is ON.) The RUN3 signal is ON even during the DC injection brake operation, and the
signal is OFF when the inverter stops.

 Operation under Real sensorless vector control and PM sensorless vector control
• When the inverter is ready for operation, the Inverter operation ready (RY) signal turns ON (and stays ON during
operation).
• When the inverter output frequency reaches the setting of Pr.13 Starting frequency or higher, the Inverter running (RUN)
turns ON. The signal is OFF during an inverter stop, during the DC injection brake operation, during tuning at start-up, or
during zero speed control.
• The Inverter running 2 (RUN2) signal is ON while the inverter is running or while the start command signal is ON. (When
the inverter's protective function is activated or the MRS signal is ON, the RUN2 signal turns OFF.)
