 Inverter operation ready signals (RY, RY2 signals) 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.

*1 The signal is OFF during power failure or undervoltage.
*2 This means the state during a fault occurrence or while the MRS signal is ON, etc.
*3 The signal is OFF while power is not supplied to the main circuit.
 Operation under Real sensorless vector control, 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 pre-excitation.
• 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.)
• The Inverter running and start command ON (RUN3) signal is ON while the inverter is running or while the start command
signal is ON.
• The RUN2 and RUN3 signals are also ON when the start command signal is ON or during pre-excitation with the speed
command value 0. (However, the RUN2 signal is OFF during pre-excitation with the LX signal ON.)
