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).
Option
Code
00
Valid for inputs:
Required settings
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 [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.
