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.
• The signal output for the PLC function (see
Pr.289 setting (not filtered for responsivity).
 Inverter operation ready signal (RY signal) and Inverter running signals
(RUN and 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 (RUN)
signal turns 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.

• To use the RY, RUN, or RUN3 signal, set the corresponding number selected from the following table in any of Pr.190 to
Pr.196 (Output terminal function selection) to assign the function to an output terminal.
