When the inverter is ready to operate, the output of the operation ready signal (RY) is on. (It is also on during inverter running.)
When the output frequency of the inverter rises to or above Pr. 13 Starting frequency , the output of the inverter running signal
(RUN) is turned on. During an inverter stop or DC injection brake operation, the output is off.
When using the RY and RUN signals, assign functions to Pr.190 to Pr.192 (output terminal selection function) referring to the
