signals (RUN) is turned on. During an inverter stop or DC
injection brake operation, the output is off.
⋅ For the RUN3 signal, output is on while the inverter running
and the start signal is on.
(For the RUN3 signal, output is on if the starting command is
on even when the inverter protective function is activated or
the MRS signal is on.)
⋅ The output is on during DC injection brake operation and off
during an inverter stop.
