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).
Option Terminal
Code Symbol
00
RUN
Valid for inputs:
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 [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.
