Using Intelligent Output Terminals
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).

Required settings
Notes:
 The inverter outputs the [RUN] signal whenever
the inverter output exceeds the start frequency
specified by parameter . The start frequency
is the initial inverter output frequency when it turns
ON.
 The example circuit for terminal [11] 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.
