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).

RUN Run Signal ON when inverter is in Run Mode
OFF when inverter is in Stop Mode
Valid for inputs: 11, 12, AL0
– AL2
Example for terminal [11] (default output
configuration shown
– see
page 3-89 ):
Example for terminal [AL0], [AL1], [AL2] (requires
output configuration
– see
page 4-51 and 3-91 ):

Required settings (none)
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 inv
erter’s output transistor.
