 Inverter operation ready signals (RY signal) and inverter running signals
(RUN, 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 Pr.13 Starting frequency or higher, the Inverter running (RUN) 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.

• When using the RY, RUN and RUN3 signals, refer to the following and assign the functions by Pr.190 to Pr.196 (Output
terminal function selection).
