(M) Monitor display and monitor output signal
Inverter operation ready signals (RY signal) and inverter running signals (RUN, RUN3 signals)
Fig. 5-95:
– When the inverter is ready for operation, the Inverter operation ready (RY) signal turns ON
(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.
– 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.
● According to the inverter condition, the ON/OFF operation of each signal is as shown below.
