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 common).
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.

Notes:
• The inverter outputs the [RUN] signal
whenever the inverter output exceeds the start
frequency specified by parameter B082. The
start frequency is the initial inverter output
frequency when it turns ON.
