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).

Description
00 RUN Run Signal ON when inverter is in Run Mode
OFF when inverter is in Stop Mode
Valid for outputs:
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 [12] 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.
