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).

OFF
when inverter is in Stop Mode
Valid for inputs:
11, 12, AL0 – AL2
Required settings
(none)
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.
Example for terminal [11] (default output
configuration shown see
page 59
):
Example for terminal [AL0], [AL1], [AL2] (requires
output configuration see

):

page 16,17.
