Run Signal
When the [RUN] signal is selected as an
intelligent output terminal, the inverter
outputs a signal on that terminal when it is in
Run Mode. The output logic is active low, and
is the open collector type (switch to ground).

NOTE: The example circuit in the table above drives a relay coil. Note the use of a
diode to prevent the negative-going turn-off spike generated by the coil from damaging
the inverter’s output transistor.

The inverter outputs the [RUN] signal whenever the
inverter output exceeds the start frequency specified
by parameter B_82. The start frequency is the initial
inverter output frequency when it turns ON.
