Parameter
Inverter operation ready signal (RY) and inverter running signal (RUN)
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 out-
put 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 or RUN signal, set "11 (source logic)" or "111 (sink logic)" (RY) or "0 (source
logic)" or "100 (sink logic)" (RUN) to any of Pr. 190, Pr. 192 or Pr. 197 to assign the function to
the output terminal.
