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).

Notes:

Inverter output

RUN

• The inverter outputs the [RUN] signal whenever the

terminal circuit

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-

RY

going turn-off spike generated by the coil from

damaging the inverter’s output transistor.
