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 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.
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).
