Run Signal

228
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).

RUN Run Signal
Valid for inputs: 11, 12, AL0 - AL2
Required settings: (none)
Notes:
• The inverter outputs the [RUN] signal when-
ever the inverter output exceeds the start fre-
quency specified by parameter . 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.
