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).

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 66):
Example for terminal [AL0], [AL1], [AL2] (requires
output configuration see page 66):
See I/O specs on page 21,22.
