Using Intelligent Output Terminals Section 4-6
4-6-5 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).

State Description
00 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 135):
Required settings: (none)
Notes:
• The inverter outputs the [RUN] signal when-
ever the inverter output exceeds the start fre-
quency specified by parameter B082. The
start frequency is the initial inverter output fre-
quency 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 [AL0],
[AL1], [AL2] (requires output
configuration – see page 199
and page 135):
