Parameter Function assignment of external terminals
FR-A700 EC 6 - 303
Inverter operation ready signal (RY, RY2 signal) and inverter running signal (RUN, RUN2,
RUN3 signal) under V/f control and advanced magnetic flux vector control
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.
The output of the RUN3 signal is on when the inverter running and start signals are on. (For the
RUN3 signal, output is on if the starting command is on even when the inverter protective func-
tion is activated or the MRS signal is on.)
The output is on during DC injection brake operation and off during an inverter stop.
This signal turns OFF during power failure or undervoltage.
