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).
NOTE: The example circuit in the table above 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.

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

Required settings: (none)
Notes:
•
The inverter outputs the [RUN] signal whenever the
inverter output exceeds the start frequency specified
by parameter B_82. The start frequency is the initial
inverter output frequency when it turns ON.
