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).

Valid for outputs:

Required settings:

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.
The example circuit for terminal [12] 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.
