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).
when inverter is in Run Mode
when inverter is in Stop Mode
Example for terminal [11] (default output
configuration shown see page 66):
Example for terminal [AL0], [AL1], [AL2] (requires
output configuration see page 66):
See I/O specs on page 23, 24.
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 inverter’s output transistor.
